redhat/Makefile: Add RHTEST

For a long time we have wanted a mechanism by which we could do a 'test
run' of Makefile targets.  Make has built-in options '-n, --just-print,
--dry-run, --recon' that can be added on the command line that allow users
to show the output for commands but not execute them.

However, as explained in the Make manual [1], Makefile lines beginning
with a '+' will still be executed if '-n' is specified.

Add a RHTEST variable that is set to 1 if '-n' (or any of the other
'dry run' parameters) is added to the make command.  Modify the scripts to
return without executing if RHTEST is set.
