[RFA/testsuite] New testcase for set/unset/show substitute-path

Hello,

Here is a first try at implementing a testcase for the new
substitute-path commands. I'm only testing the manipulation
of the list of substitution rules at this point, because I still
don't see how to implement something that would test the actual
substitution and work in all cases. I figured this is better than
nothing for now.

        * gdb.base/subst.exp: New testcase.

Tested on x86-linux. OK to apply?

Thanks,
-- 
Joel
