gdb/testsuite: eliminate gdb_suppress_tests mechanism

There is a lot of support code for the test suppression mechanism.  But
as far as I know, it is not useful.  The gdb_suppress_tests proc is in
fact disabled with this comment that has been there since forever:

    return;  # fnf - disable pending review of results where
             # testsuite ran better without this

I suggest to just remove everything related to test suppression, that
removes some unnecessary complexity from the support code and the tests.
