repro: Restore makepkg.conf from devtools

The commit ceeead1 the portion of code
that copies the devtools makepkg.conf from the temporary container to
the build container. That was fine since it wouldn't work with EPHEMERAL
containers implementation anyway :)

This patch reintroduces the devtools makepkg.conf correctly into the
build container.
