selftests: ALSA: Skip timer tests when device is unavailable

Browse Source 
When CONFIG_SND is disabled, opening /dev/snd/timer fails and the
userspace timer tests report failures even though the test environment
does not support ALSA timers.

Skip the affected tests when opening the timer device fails because the
device is unavailable. Continue to report unexpected open failures as
test failures.
