stm32: remove useless modulo

Browse Source 
The RTC delay is always less than a day (see the assert at the beginning
of set_rtc_alarm), so remove the useless module to save a few bytes of
flash.

Signed-off-by: Vincent Palatin <vpalatin@chromium.org>

BRANCH=samus
BUG=none
TEST=make buildall
and see the zinger firmware is smaller by 16 bytes
(more than the 8 bytes I need to submit the following CL)
