fix tarball names generated by Makepkgs

Currently Makepkgs generates the source tarball as dmapi-version.src.tar.gz,
which is not what we used for recent releases and not what most other open
source packages do.  Change it to dmapi-version.tar.gz, and rename the
binary tarball to dmapi-version.bin.tar.gz
