Subject: [PATCH] makepkg: treat pkgrel more similarly to pkgver

This is perfectly fine with libalpm; it was only makepkg that was more
strict with pkgrel than pkgver.

Further, the former error message about invalid pkgrel formats claimed that
pkgrel was a "decimal", which would mean that `1.1 == 1.10`.  This was not
the case; alpm parsed pkgrel as a version, not a decimal.  In that light,
enforcing /[0-9]+(\.([0-9]+)?/ on a version spec seems silly.
