Update fallback implementation of missing libc functions

  This commit updates realpath.c from
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/realpath.c?rev=1.14;content-type=text/plain
and lisp/env.c from
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/getenv.c?rev=1.10;content-type=text/plain
and
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/setenv.c?rev=1.13;content-type=text/plain

  The update reason is to replace files under "4 clause BSD", that
is considered problematic or require special documentation notation
or conditions when redistributing free software.
