    [gdb/testsuite] Fix gdb.base/run-attach-while-running.exp

    With a testsuite setup modified to make expect wait a little bit longer for
    gdb output (see PR27957), I reliably run into:
    ...
    27        return SYSCALL_CANCEL (nanosleep, requested_time, remaining);^M
    (gdb) ^M
    Thread 2 "run-attach-whil" stopped.^M
    0x00007f13c85a74c0 in __GI___nanosleep () at nanosleep.c:27^M
    27        return SYSCALL_CANCEL (nanosleep, requested_time, remaining);^M
    FAIL: gdb.base/run-attach-while-running.exp: threaded=1: \
      run-or-attach=attach: non-stop=on: test: attach to process (timeout)
    ...

    The problem is that we're trying to match the gdb_prompt using gdb_test
which
    uses '$gdb_prompt $'.  The terminating '$' prevents the match.

    Fix this by rewriting the gdb_test into a gdb_test_multiple and dropping
the
    '$'.

    Tested on x86_64-linux.
