gdb: use infrun_debug_printf in print_target_wait_results

The code in print_target_wait_results uses a single call to debug_printf
in order to make sure a single timestamp is emitted, despite printing
multiple lines.  The result is:

    941502.043284 [infrun] target_wait (-1.0.0, status) =
    [infrun]   649832.649832.0 [process 649832],
    [infrun]   status->kind = stopped, signal = GDB_SIGNAL_TRAP

I find this decision a bit counter productive, because it messes up the
alignment of the three lines.  We don't care that three (slightly
different) timestamps are printed.

I suggest to change this function to use infrun_debug_printf, with this
result:

    941601.425771 [infrun] print_target_wait_results: target_wait (-1.0.0 [process -1], status) =
    941601.425824 [infrun] print_target_wait_results:   651481.651481.0 [process 651481],
    941601.425867 [infrun] print_target_wait_results:   status->kind = stopped, signal = GDB_SIGNAL_TRAP

Note that the current code only prints the waiton_ptid as a string
between square brackets if pid != -1.  I don't think this complexity is
needed in a debug print.  I made it so it's always printed, which I
think results in a much simpler function.

gdb/ChangeLog:

	* infrun.c (print_target_wait_results): Use infrun_debug_printf.
