Move some tests from cpan/version to t/run

Commit fb7942811c8097ed2e61fd35a90345226546176a recently moved
version.pm to cpan.  Earlier, in commit
b127e37e51c21b0a36755dcd19811be931a03d83, I had added tests to version's
.t that arguably belonged elsewhere.  I did this because I thought that
this .t was the only one around that had the infrastructure already
written to allow such tests to easily be added, and it was in /lib so
p5p controlled it.  (That infrastructure being finding locales with the
decimal point not a dot.)  Since then, I found that t/run/locale.t has
similar infrastructure.  Given that version now may end up being cpan
upstream, I thought it best to move those tests to t/run/locale.t

I notice that changes to this .t prior to these no longer were careful
to avoid 'use locale' in case the platform doesn't support it, and there
have been no field problems; so I just went ahead and did a 'use locale'
too.
