checkpkg: set makepkg vars from build root to support none host archs

When building for an architecture different from the host, the correct
old package was downloaded as "$copydir"'s pacman was configured with
the target CARCH, but checkpkg doesn't know this and tries to search the
cache for host CARCH instead, producing the following error:

`==> ERROR: tarball not found for package: xxx`

This change fixes this by passing the appropriate makepkg config
explicitly, so that checkpkg behaves consistently.
