    Fix gdbserver/linux target_waitstatus logging assert
    
    Turning on debug output in gdbserver leads to an assertion failure if
    gdbserver reports a non-signal event:
    
        [threads] wait_1: LWP 3273770: extended event with waitstatus status->kind = EXECD, execd_pathname = gdb.threads/non-ldr-exc-1/non-ldr-exc-1
        [threads] wait_1: Hit a non-gdbserver trap event.
      ../../src/gdbserver/../gdb/target/waitstatus.h:365: A problem internal to GDBserver has been detected.
      sig: Assertion `m_kind == TARGET_WAITKIND_STOPPED || m_kind == TARGET_WAITKIND_SIGNALLED' failed.
    
    Fix it in the obvious way, using target_waitstatus::to_string(),
    resulting in, for example:
    
      [threads] wait_1: ret = LWP 1542412.1542412, status->kind = STOPPED, sig = GDB_SIGNAL_TRAP
