Fix racy test in gdb.threads/thread-specific-bp.exp

I see the following test fail from time to time, due to the racy test
in gdb.threads/thread-specific-bp.exp.

FAIL: gdb.threads/thread-specific-bp.exp: non-stop: continue to end (timeout)

This patch changes gdb_test to gdb_test_multiple to match prompt only
instead of both prompt and anchor.

* gdb.threads/thread-specific-bp.exp (check_thread_specific_breakpoint):
Use gdb_test_multiple, and don't match anchor.
