tar: tar -x without --incremental no longer sets atime again

* src/extract.c (set_stat): Use UTIME_OMIT rather than UTIME_NOW.
The UTIME_NOW was there only to emulate the previous behavior of
using the current time, and the previous behavior was there only
because before we started assuming POSIX.1-2008 there was no
portable way to get the effect of UTIME_NOW.
