[PATCH] selftests: rtc: Increase test timeout so that all tests run

["Nícolas F. R. A. Prado" <nfraprado@collabora.com>]

The timeout setting for the rtc kselftest is currently 90 seconds.
However, two of the tests set alarms, which take one minute to complete
each. So the timeout should be at least 120. Set it to 180, so that all
tests are able to complete and still have some slack.

This issue was discovered as part of adding the rtc kselftest to run on KernelCI
for the rk3399-gru-kevin device, which uses rtc-cros-ec as the RTC driver.

The output log with the current timeout is shown in [1]. As can be seen, the
whole test times out before the alarm_wkalm_set_minute test has had a chance to
complete:

	# #  RUN           rtc.alarm_wkalm_set_minute ...
	# # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 11/01/2022 23:03:00.
	#
	not ok 1 selftests: rtc: rtctest # TIMEOUT 90 seconds

With the increased timeout, as shown in [2], the alarm_wkalm_set_minute test
does complete its run:

	# #  RUN           rtc.alarm_wkalm_set_minute ...
	# # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 12/01/2022 15:54:00.
	# #            OK  rtc.alarm_wkalm_set_minute
	# ok 7 rtc.alarm_wkalm_set_minute
	# # FAILED: 6 / 7 tests passed.

The fact that the alarm_alm_set_minute test times out on its own is probably an
issue with the rtc-cros-ec driver. Still, since the tests are independent, all
of them should be able to run regardless of how long each one takes (so,
assuming the worst case scenario).
