[PATCH] makepkg: add source signing PGP keys to package if available

[Allan McRae]

Arch Linux is adding source signing PGP keys to their package source
tree alongside PKGBUILDs in the form keys/pgp/$fingerprint.asc. As the
PGP keyserver infrastructure is a mess, this helps other people validate
sources in a PKGBUILD.

Add the keys to source packages if found alongside the PKGBUILD.

I won't be committing this until the relevant Arch devtools patch is
accepted so that the keys/pgp/ path is finalised.
