sys_getopt has now its global status variables prefixed with sys_getopt_ Let's fix the use here. Note this worked as Zephyr's POSIX_C_LIB_EXT keeps a replica of these variables without the prefix, and it is enabled by default. And since sys_getopt was split from POSIX_C_LIB_EXT this component only needs to enable GETOPT and no the whole POSIX_C_LIB_EXT.
