Jesús Daniel Colmenares Oviedo 436af5715c flua: Fix SIGSEGV in lua_chown when uid/gid doesn't exist ...

When lua_chown is used to call chown(2) internally, it first resolves
the user and/or group by calling the getpwnam_r(3) and getgrnam_r(3)
functions, respectively. However, although it checks for errors, it does
not check when entries are not found (which is not an error), which
means that the buffer will be set to NULL, and since lua_chown attempts
to access the NULL structure, it will receive a SIGSEGV signal.
