mke2fs: write new group descriptors with the appropriate checksum

Update mke2fs to use the helper function to determine if group
descriptors should have checksums calculated.  Since metadata_csum
supersedes uninit_bg, quietly drop uninit_bg if metadata_csum is set,
so that older kernels don't get confused.
