Fix files utility not to set timestamps

Browse source 
Commit f33b96b1 (v4.3.12) made files again set timestamps.  That was
intentionally suppressed in commit 990eb46b (v4.3.10), because it
facilitates attacks against the PRNG.  Commit 8f98e53a (v4.3.0) had
added it as a feature.

Fix by making files's main() pass new flag EFF_NOTIME to ef_open().
Implement the flag in do_write().
