Merge bitcoin/bitcoin#32448: contrib: remove bdb exception from FORTIFY check

f9dfe8d contrib: remove bdb exception from FORTIFY check (fanquake)

Pull request description:

  BDB has been removed (#28710), so we no-longer need to ignore functions from BDB in this check.

  Guix building this branch, and looking for `*_chk` functions across all binaries produces:
  ```
  # nm -C * | grep -i _chk | sort | uniq
                   U __fdelt_chk@GLIBC_2.15
                   U __fprintf_chk@GLIBC_2.3.4
                   U __fread_chk@GLIBC_2.7
                   U __longjmp_chk@GLIBC_2.11
                   U __memcpy_chk@GLIBC_2.3.4
                   U __printf_chk@GLIBC_2.3.4
                   U __snprintf_chk@GLIBC_2.3.4
                   U __sprintf_chk@GLIBC_2.3.4
                   U __stack_chk_fail@GLIBC_2.4
                   U __vsnprintf_chk@GLIBC_2.3.4
  ```
