mke2fs.conf: add back missing uninit_bg feature flag

Commit 0da058af9f88: "mke2fs.conf: don't enable metadata_csum by
default" removed metadata_csum without adding back the uninit_bg flag
--- which had the net result of causing file systems to take a long
time to mke2fs, since this caused all of the block group metadata to
be initialized.
