More sanity.sh problems on cvs 1.11.2

Hello,

I already reported this one for "modules5-8":
It seems, that cvs honours (at least partly) env vars like TEMP, TMP,
TMPDIR... but the check-script is caught of guard by this.
(Maybe sanity.sh should unset those vars, right at the start (as it already 
does for 'LC...') ?)

This happens for quite a bunch of checks, not just  "modules5-8".

Second problem:
I'm using cvs on HPUX 10.20
Here 'rsh' is the restricted sh, not remote.
This ones calls itself 'remsh'.
So, if the OS  is HPUX (uname -s), CVS_RSH needs to be remsh, otherwise the 
remote tests will fail too.

With those corrections, "make check" ran successful.
