[PATCH] mke2fs: recognize mke4fs program name

[Eric Sandeen <sandeen@redhat.com>]

We shipped "mke4fs" alongside mke2fs in RHEL5, so that ext4-capable
utilities could be installed without disturbing the venerable e2fsprogs-1.39
shipped in RHEL5 from the beginning.  But it surprised some users that
"mke4fs" created ext2 filesystems by default rather than ext4.
While it was my intent to have the renamed binaries behave exactly
like the stock ones, it seems that there is some precedence for
handling "mkeNfs" in the code, so seems reasonable to add 
mke4fs -> ext4 as well.

This probably doesn't matter much to upstream, but it seems consistent
with the existing code, below, if you'd like to include it.
