    [gdb/testsuite] Fix gdb.threads/thread-specific-bp.exp on native-gdbserver

    With test-case gdb.threads/thread-specific-bp.exp and target board
    native-gdbserver I run into:
    ...
    (gdb) PASS: gdb.threads/thread-specific-bp.exp: non_stop=off: thread 1
selected
    continue^M
    Continuing.^M
    Thread-specific breakpoint 3 deleted - thread 2 no longer in the thread
list.^M
    ^M
    Thread 1 "thread-specific" hit Breakpoint 4, end () at \
      thread-specific-bp.c:29^M
    29      }^M
    (gdb) FAIL: gdb.threads/thread-specific-bp.exp: non_stop=off: \
      continue to end (timeout)
    ...

    The problem is that the test-case tries to match the "[Thread ... exited]"
    message which we do see with native testing:
    ...
    Continuing.^M
    [Thread 0x7ffff746e700 (LWP 7047) exited]^M
    Thread-specific breakpoint 3 deleted - thread 2 no longer in the thread
list.^M
    ...

    The fact that the message is missing was reported as PR remote/30129.

    We could add a KFAIL for this, but the functionality the test-case is
trying
    to test has nothing to do with the message, so it should pass.  I only
added
    matching of the message in commit 2e5843d87c4 ("[gdb/testsuite] Fix
    gdb.threads/thread-specific-bp.exp") to handle a race, not realizing doing
so
    broke testing on native-gdbserver.

    Fix this by matching the "Thread-specific breakpoint $decimal deleted"
message
    instead.

    Tested on x86_64-linux.
