Subject: kselftests: timers: leap-a-day: Change default arguments to help test runs

From: John Stultz <john.stultz@linaro.org>

commit 98b74e1f31045a63f6148b2d129ca9bf244e24ab upstream.

Change default arguments for leap-a-day to always set the time
each iteration (rather then waiting for midnight UTC), and to
only run 10 interations (rather then infinite).

If one wants to wait for midnight UTC, they can use the new -w
flag, and we add a note to the argument help that -i -1 will
run infinitely.
