[builder] gdb_check_step: remove gdb.gdb/selftest.exp

Hi,

I just committed the following update to builder:

    selftest.exp is bad (flaky), just keep the gdb and gdbserver
    unittest.exp for the CI runs.

builder.sourceware.org does two builds for gdb.  quick CI builds that
just build gdb and gdb-server and run a small amount of tests that are
known to reliably PASS. If any of this fails it will sent email to the
gdb-testers mailinglist and the author of the commit.
https://builder.sourceware.org/buildbot/#/builders?tags=gdb

It also does full builds for binutils-gdb as a whole plus the full
testsuite both against gcc and clang. These do record all logs in
bunsendb but doesn't sent emails:
https://builder.sourceware.org/buildbot/#/builders?tags=binutils-gdb

With the removal of the selftest.exp there are only two unittest.exp
tests (one for gdb and one for gdbserver). This does seem very
minimal. Could someone suggest stable, known good passing tests that
should be added because when they do start failing it really is a
regression that should be flagged?

Note that the intention is to also allow a trybot that runs the same
set of CI tests so it can be used as pre-commit check.

Cheers,

Mark

P.S. There were same bad failing emails today. Our apologies, that was
a bunsen upload typo.
