Subject: [BUGFIX PATCH -tip] perf tools: Add OPT_END to option array of
	perf-trace

Add OPT_END to option array of perf-trace for fixing a SEGV bug when
showing perf-trace help message.

 ./perf trace -h

 usage: perf trace [<options>] <command>

    -D, --dump-raw-trace  dump raw trace in ASCII
    -v, --verbose         be more verbose (show symbol address, etc)
    -f, Segmentation fault

With this patch:
 ./perf trace -h

 usage: perf trace [<options>] <command>

    -D, --dump-raw-trace  dump raw trace in ASCII
    -v, --verbose         be more verbose (show symbol address, etc)
