[PATCH 20/86] perf trace beauty open flags: Move RDRW to the start of the output

Arnaldo Carvalho de Melo

From: Arnaldo Carvalho de Melo <acme@redhat.com>

We were getting:

62597.859 ( 0.005 ms): TaskSchedulerF/18107 fcntl(fd: 194, cmd: GETFL) = LARGEFILE|RDWR

Instead of the more familiar (from looking at strace output):

62597.859 ( 0.005 ms): TaskSchedulerF/18107 fcntl(fd: 194, cmd: GETFL) = RDWR|LARGEFILE

Fix it.
