hw/rtc/m48t59: Use 64-bit arithmetic in set_alarm()
In the m48t59 device we almost always use 64-bit arithmetic when
dealing with time_t deltas. The one exception is in set_alarm(),
which currently uses a plain 'int' to hold the difference between two
time_t values. Switch to int64_t instead to avoid any possible
overflow issues.
