  test: Fix tst.symbols.c

Skip symbols (e.g., ftrace_trampoline) in module __builtin__ftrace
since we cannot load the module ELF.

Fix the check for duplicate symbols in the "lookup by name" test.
Specifically, we were checking for duplicates when dtrace_lookup_by_name()
failed.  Check for duplicates when that function succeeds.  This fix
is necessitated by commit 8151fb85 "htab reduction: symtab", which
makes it hard for us to know which duplicate will be chosen.

The cpu member has moved back out of task_struct
to signal_struct (which it moved from in 4.9).

  test: use more reliable way of finding kernel versions

In several places we were using cut and/or awk to find kernel versions:
in each case the code used worked for versions like 5.15 or 5.11.4 but
failed for things like 5.15+ or 5.15-00024-g679b45e057b4-dirty,
because they are splitting fields on dots alone.

The rarely-used and little-known grep -o can do all of this more simply
and reliably, since it can split fields using full regular expressions
(and thus can easily be told that what we are looking for here is a run
of digits only).

  README revisions

Mention the toolchain CTF system, deprecate libdtrace-ctf,
mention newer kernels, mention the kernel git trees much
higher up, don't mention wireshark and libpcap.

Not sure if it's syntactically valid markdown :( the internal hyperlinks
don't seem to point to anything, but maybe Github creates them for us.
If it does, I'm not sure if I got their names right...
