minstall: Don't copy over an identical file
The rationale here is to avoid updating a timestamp for a file that
hasn't changed. Needless updates of the timestamp can ripple into
other projects, (xserver, etc.), useless recompiling due to a
'make install' in mesa that didn't actually change anything.
