makepkg: allow overriding arch in split packages

This allows building a mixture of binary and arch=any packages.
Fixes FS#15955.

The value of CARCH is no longer overridden to "any" in when arch=any
is used and the assigning of the "any" arch is delayed to during the
packaging stage. Adjustments were required to fix installing and
checking for pre-built packages of varing arches.
