d451b60d22576dff7a2c8d6a8b5880d9d69e397c guix-verify: Non-zero exit code when anything fails (Carl Dong)
Pull request description:
```
Previously, if verification fails, the correct message will be printed,
but the exit code would still be 0.

Pull request description:
Based on: #22075
Code reviewers: I recommend reading the new `guix-{attest,verify}` files instead of trying to read the diff
The following changes resolve many usability improvements which were pointed out to me:
1. Some maintainers like to extract their "uncodesigned tarball" inside the `output/` directory, resulting in the older `guix-attest` mistakenly attesting to the extracted contents
2. Maintainers whose GPG keys reside on an external smartcard often need to physically interact with the smartcard as a way to approve the signing operation, having one signature per platform means a lot of fidgeting
3. Maintainers wishing to sign on a separate machine now has the option of transferring only a subtree of `output/`, namely `output/*/SHA256SUMS.part`, in order to perform a signature (you may need to specify an `$OUTDIR_BASE` env var)
4. An `all.SHA256SUMS` file should be usable as the base `SHA256SUMS` in bitcoin core torrents and on the release server.
For those who sign on an separate machine than the one you do builds on, the following steps will work:
1. `env GUIX_SIGS_REPO=/home/achow101/guix.sigs SIGNER=achow101 NO_SIGN=1 ./contrib/guix/guix-attest`
2. Copy `/home/achow101/guix.sigs/<tag>/achow101` (which does not yet have signatures) to signing machine
3. Sign the `SHA256SUMS` files:
```bash
for i in "<path-to-achow101>/*.SHA256SUMS"; do
gpg --detach-sign --local-user "<your-key-here>" --armor --output "$i"{.asc,}
done
```
5. Upload `<path-to-achow101>` (now with signatures) to `guix.sigs`
-----
After this change, output directories will now include a `SHA256SUMS.part` fragment, created immediately after a successful build:
```

These `SHA256SUMS.part` fragments look something like:

```
Meaning that they are valid `SHA256SUMS` files when `sha256sum --check`'d at the `guix-build-*/output` directory level
When `guix-attest` is invoked, these `SHA256SUMS.part` files are combined and sorted (by `-k2`, `LC_ALL=C`) to create:
1. `noncodesigned.SHA256SUMS` for a manifest of all non-codesigned outputs, and
3. `all.SHA256SUMS` for a manifest of all outputs including non-codesigned outputs
Then both files are signed, resulting in the following `guix.sigs` hierarchy:
```

Pull request description:
Adds replacements for `gsign` and `gverify`.
Personally I'm not a big fan of using the word "sign" as it's been used to refer to both codesigning and GPG signing.
