Configuration: only produce a new configdata.pm if it has changed contents

The goal is to avoid having too much of the OpenSSL source rebuilt
because configdata.pm got a new time stamp.  The conditions for
updating configdata.pm are now:

1.  its time stamp is older than Configure's, or...
2.  its contents has changed.

Fixes #16377
