perf
It is mostly used only to generate string tables, not to build perf, so
move it to the tools/perf/trace/beauty/include/ hierarchy, that is used
just for scraping.
This is a something that should've have happened, as happened with the
linux/socket.h scrapper, do it now as Ian suggested while doing an
audit/refactor session in the headers used by perf.
No other tools/ living code uses it, just <linux/mount.h> coming from
either 'make install_headers' or from the system /usr/include/
directory.

After gnulib update sed stopped matching `[[:space:]]*+' as before,
causing the following compilation error:
In file included from builtin-trace.c:719:
trace/beauty/generated/fsconfig_arrays.c:2:3: error: expected expression before ']' token
2 | [] = "",
| ^
trace/beauty/generated/fsconfig_arrays.c:2:3: error: array index in initializer not of integer type
trace/beauty/generated/fsconfig_arrays.c:2:3: note: (near initialization for 'fsconfig_cmds')
Fix this by correcting the regular expression used in the generator.
Also, clean up the script by removing redundant egrep, xargs, and printf
invocations.
Committer testing:
