scripts/gdb: fix 'qemu coroutine' when users selects a non topmost stack frame

The code that dumps the stack frame works like that:
* save current registers
* overwrite current registers (including rip/rsp) with coroutine snapshot
in the jmpbuf
* print backtrace
* restore the saved registers.

If the user has currently selected a non topmost stack frame in gdb,
the above code will still restore the selected frame registers,
but the gdb will then lose the selected frame index, which makes it impossible
to switch back to frame 0, to continue debugging the executable.

Therefore switch temporarily to the topmost frame of the stack
for the above code.

qemu-gdb: allow using glibc_pointer_guard() on core dumps

get_fs_base() cannot be run on a core dump, because it uses the arch_prctl
system call. The fs base is the value that is returned by pthread_self(),
and it would be nice to just glean it from the "info threads" output:

* 1 Thread 0x7f16a3fff700 (LWP 33642) pthread_cond_wait@@GLIBC_2.3.2 ()
^^^^^^^^^^^^^^

but unfortunately the gdb API does not provide that. Instead, we can
look for the "arg" argument of the start_thread function if glibc debug
information are available. If not, fall back to the old mechanism.
