release: Add security/export checks to gitian and fix current failures
- fix parsing of BIND_NOW with older readelf
- add _IO_stdin_used to ignored exports

For details see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=634261#109

- add check-symbols and check-security make targets

These are not added to the default checks because some of them depend on
release-build configs.

- always link librt for glibc back-compat builds

glibc absorbed clock_gettime in 2.17. librt (its previous location) is safe to
link in anyway for back-compat.

Fixes #7420

- add security/symbol checks to gitian

579b863cd7 devtools: Add security-check.py
Perform the following ELF security checks:

- PIE: Check for position independent executable (PIE), allowing for address space randomization
- NX: Check that no sections are writable and executable (including the stack)
- RELRO: Check for read-only relocations, binding at startup
- Canary: Check for use of stack canary

Also add a check to symbol-check.py that checks that only the subset of
allowed libraries is imported (to avoid incompatibilities).
