Subject: [PATCH 4/4] 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 is not
the case; alpm parses pkgrel as a version, not as a decimal.  In that
light, enforcing /[0-9]+(\.([0-9]+)?/ on a version spec seems silly.
