libc/grp: Added stubbed implementations of getgrgid, getgrgid_r, getgrnam, getgrnam_r, and initgroups. These functions are essentially stubs pretending that NuttX supported groups and that the only configured group in the system was 'root' with gid 0. The intend is not to provide meaningful new features, but to ease porting of foreign source code to NuttX.
