ab3316119f perf beauty: Move uapi/linux/mount.h copy out of the directory used to build 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.

2e1daee14e perf beauty: Fix fsconfig generator
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:

Continues to work:

  $ cat tools/perf/trace/beauty/fsconfig.sh
  #!/bin/sh

  if [ $# -ne 1 ] ; then
  	linux_header_dir=tools/include/uapi/linux
  else
  	linux_header_dir=$1
  fi

  linux_mount=${linux_header_dir}/mount.h

  printf "static const char *fsconfig_cmds[] = {\n"
  ms='[[:space:]]*'
  sed -nr "s/^${ms}FSCONFIG_([[:alnum:]_]+)${ms}=${ms}([[:digit:]]+)${ms},.*/\t[\2] = \"\1\",/p" \
  	${linux_mount}
  printf "};\n"
