Subject: makepkg: remove support for PKGBUILDs without a package() function

Not having a package() function means all building occurs as root
and repackaging can lose permissions.  Given the use of package()
functions has been around for years and we deprecated not having
one in pacman-4.1, we can remove support for PKGBUILDs without
package() functions altogether. However, keep PKGBUILDs that have
neither a build() or package() function working.
