lib: Add getopt-cdefs.h for getopt_long update.
This was modified slightly from Gnulib. In Gnulib, it expects the @HAVE_SYS_CDEFS_H@ to be replaced. Instead, we can set HAVE_SYS_CDEFS_H on systems that have it and avoid copying another file into the build directory. Since we are not using gnulib-tool, copying extra files requires extra build system updates (and special handling with CMake) so we should avoid when possible.
