Revise file stamp in state.py

Removed information (ctime) that was causing spurious
"you modified it" warnings.

[apenwarr: This was not quite right.  ctime includes some things we
don't want to care about, such as link count, so we have to remove it.
But it also notices changes to st_uid, st_gid, and st_mode, which we do
care about, so now we have to include those explicitly.]
