CURRENT_TIME macro is not y2038 safe on 32 bit systems.

The patch replaces all the uses of CURRENT_TIME by
current_time().

This is also in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe. current_time() is also planned to be transitioned
to y2038 safe behavior along with this change.

CURRENT_TIME macro will be deleted before merging the
aforementioned change.

This is all good, and I have no objections to it being merged for 4.12.
If it isn't this change is already queued up for the apparmor 4.13
merge
