CMake: Don't check for optreset if using replacement getopt_long

Browse Source 
If <getopt.h> had optreset but not getopt_long, xz used optreset while
the replacement getopt_long doesn't support optreset. I'm not aware of
any relevant system where bug is possible. Autotools build didn't have
this bug.

Fixes: af66cd585902 ("CMake: Add support for replacement getopt_long (lib/getopt*).")
