makepkg: get package version with overrides

When epoch, pkgver and/or pkgrel were overridden in a split package
function, makepkg failed hard finding the real version for checking
if packages were already built or trying to install packages. Fix
the get_full_version function to deal with overrides and return the
actual package version.
