There is no scrape script yet for those, but the warning pointed out we
need to update the array with the F_LINUX_SPECIFIC_BASE entries, do it.

Now 'perf trace' can decode that cmd and also use it in filter, as in:

  root@number:~# perf trace -e syscalls:*enter_fcntl --filter 'cmd != SETFL && cmd != GETFL'

This addresses this perf tools build warning:

  diff -u tools/perf/trace/beauty/include/uapi/linux/vhost.h include/uapi/linux/vhost.h

But this specific process, usually boring, this time around catch a
problem, namely the addition of VDPA_GET_VRING_SIZE used an ioctl number
already taken, which went on unnoticed and only got caught when the
tools/perf/trace/beauty/vhost_virtio_ioctl.sh script was run as part of
the perf tools process of updating the tools copies of system headers it
uses for creating id->string tables that, well, broke the perf tools
build because there were multiple initializations in the strings table
for the 0x80 entry...

I'm adding here a link to the discussion, that is lacking in the fix for
the reported problem, and a quote from one of the developers involved:

"Thanks a lot for taking care of this! So given the header is actually
buggy pls hang on to this change until I merge the fix for the header
(you were CC'd on the patch).  It's great we have this redundancy which
allowed us to catch the bug in time, and many thanks to Namhyung Kim for
reporting the issue!"

This is here as a hint for anyone thinking about ways to automate
checking these issues in a more automated way... ;-)
