Konstantin Belousov dec68aeff8 libc/stdlib/getenv.c: always allocate new environment 
in particular, if the old environment is NULL.

Among making it less surprising for userspace to observe NULL environ,
the change also prevents NULL deref in __rebuild_environ() when
terminating the empty as NULL environment with the NULL pointer.
