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.
