d644c45e39c45118df86692f9365d25dbba49461 build, refactor: Drop redundant `$(package)_download_file` assignments (Hennadii Stepanov)
Pull request description:
No need to specify `$(package)_download_file` when it is equal to `$(package)_file_name`.
Historically, before bitcoin/bitcoin#19817, distinct `$(package)_download_file` and `$(package)_file_name` were used for better portability (I guess) by removing `+` characters from a file name.
The only package which still use file renaming is `native_capnp`: eca694a4e7/depends/packages/native_capnp.mk (L3-L5)
