perf trace: Beautify 'fsconfig' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced fsconfig cmd
table generator.
Now it should be possible to just use:
perf trace -e fsconfig
As root and see all fsconfig syscalls with its args beautified, more
work needed to look at the command and according to it handle the 'key',
'value' and 'aux' args, using the 'fcntl' and 'futex' beautifiers as a
starting point to see how to suppress sets of these last three args that
may not be used by the 'cmd' arg, etc.
