Add more intelligent handling of the mke2fs.conf installation process

For people who are compiling mke2fs for their own use outside of a
package manager, we need to make sure the system /etc/mke2fs.conf is
sufficiently up-to-date that it won't cause problems, but at the same
time we don't want to blow away any user-specific customizations.

So if /etc/mk2fs.conf exists, but does not mention ext4dev, we will
move it aside to /etc/mke2fs.conf.e2fsprogs-old and then install the
new mke2fs.conf.  If the /etc/mke2fs.conf file exists but does mention
ext4dev, we install the new mke2fs.conf file as
/etc/mke2fs.conf.e2fsprogs-new.  In both cases we print a warning
mesage to the user so they can manually update /etc/mke2fs.conf with
any changes if they so desire.
