full webrev (complete set of changes):
http://cr.opensolaris.org/~swalker/pkg-lock-5-full/
Change Summary:
* changed unlock to truncate lock file instead of removing since the
lock file itself is only used so that it has something to use lockf() on
and to store information about the caller who acquired the lock
* added iso-8601 utc timestamp to lock file to aid debugging in trying
to determine how long a lock has been held
* updated unit tests to account for truncation/size checks
