makepkg: Add support for verifying pgp signatures

Many projects provide signature files along with the source code
archives. It's good to check these, too, when verifying the integrity
of source code archives.
Not everybody is using gpg so the verification can be disabled with
--skippgpcheck.
Additionally, only a warning is displayed when the key that signed the
source file is unknown.
