[Intel-gfx] [PATCH i-g-t] lib/igt_core: Move write_stderr out of LIBUNWIND ifdef

[Arkadiusz Hiler]

write_stderr() and __write_stderr() are defined behind ifdef on
HAVE_LIBUNWIND, but do no depend on the lib in any way.

fatal_sig_handler() uses those helpers unconditionally.

This patch just moves the code couple of lines up, so the helpers are
always available and do not break build on systems without libunwind.
