makepkg: avoid using comm for diff'ing package lists

Browse Source 
Whereas comm will check inputs to see if they're sorted (and warn when
they aren't), grep doesn't even care about ordering. In this particular
instance -- neither do we. We're only interested that the two lists are
equivalent.

Fixes FS#26580.
