In 42e7020281 creating the gpg statusfile
for a source file was split into a separate function, which used the
return code to indicate unsigned files and proto-specific errors.
However, the fallback return code was set by the final gpg invocation,
which would be 1 if the signature was somehow broken (for example, the
key was not available in the gpg keyring). As a result makepkg thought
that file did not have a signature and skipped over it rather than
erroring out.
Fix this by explicitly setting the return code for all
verify_*_signature() functions.
