[PATCHv2] git-p4: ticket expiry test: use a fake p4 to avoid use of 'sleep'

[Luke Diamand <luke@diamand.org>]

From: Luke Diamand <ldiamand@roku.com>

This tests for p4 ticket expiry by creating a ticket, and then waiting
long enough for the ticket to nearly expire. However, this is
unreliable.

Instead, create a 'fake' p4 which returns expiry times under the
control of the test script, and forwards other commands to the
real p4 executable.
