    testsuite: Fix PR threads/19422 regression + Guile regression

    The PR threads/19422 patchset added a new regression.

    Additionally below it there was already a regression if --with-guile (which
is
    default if Guile is found) was used.

    racy case #1:

    Pedro Alves:
    Not all targets support thread names, and even those that do, not all
    use the program name as default thread name -- I think that's only true
    for GNU/Linux, actually.  So I think it's best to not expect that, like:
                -re "(Thread .*|Program) received signal SIGINT.*$gdb_prompt $"

    gdb/testsuite/ChangeLog
    2016-01-22  Jan Kratochvil  <jan.kratochvil@redhat.com>

        Fix testsuite compatibility with Guile.
        * gdb.gdb/selftest.exp (send ^C to child process): Accept also Thread.
        (thread 1): New test for backtrace through signal handler.
