perf beauty socket/prctl_option: Cope with extended regexp complaint by grep

Noticed on fedora 38, the extended regexp that so far was ok for both
grep and sed now gets complaints by grep, that says '/' doesn't need to
be escaped with '\'.

So stop using '/' in sed, use '%' instead and remove the \ before / in
the common extended regexp.

perf tools: Use "grep -E" instead of "egrep"

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:

egrep: warning: egrep is obsolescent; using grep -E

fix this up by moving the related file to use "grep -E" instead.

sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf`

Here are the steps to install the latest grep:

wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
tar xf grep-3.8.tar.gz
cd grep-3.8 && ./configure && make
sudo make install
export PATH=/usr/local/bin:$PATH

This uses a copy of include/linux/socket.h that is kept in a directory
to be used just for these table generation scripts and for checking if
the kernel has a new file that maybe gets something new for these
tables.

This allows us to:

- Avoid accessing files outside tools/, in the kernel sources, that may
be changed in unexpected ways and thus break these scripts.

- Notice when those files change and thus check if the changes don't
break those scripts, update them to automatically get the new
definitions, a new socket family, for instance.

- Not add then to the tools/include/ where it may end up used while
building the tools and end up requiring dragging yet more stuff from
the kernel or plain break the build in some of the myriad environments
where perf may be built.

This will replace the previous static array in tools/perf/ that was
dated and was already missing the AF_KCM, AF_QIPCRTR, AF_SMC and AF_XDP
families.

The next cset will wire this up to the perf build process.

At some point this must be made into a library to be used in places such
as libtraceevent, bpftrace, etc.
