Subject: [PATCH] emacsMacport: don't explicitly unpack the tarballs as gzip

tar's -z flag only works for gzip-compressed tarballs. When passed a tarball
compressed with a different compressor (like xz), tar will fail to extract it.

Since tar can auto-detect a compressed tarball and use the appropriate
decompressor itself since forever, this is unecessary now.
