Instead of open-coding the "test for file, if present make a backup,
then copy the file to the new location" in multiple places, make a
single function, install(), to do all of this in one place.
Note, this does change the default x86 kernel map file saved name from
"System.old" to "System.map.old". This brings it into unification with
the other architectures as to what they call their backup file for the
kernel map file. As this is a text file, and nothing parses this from a
backup file, there should not be any operational differences.
