macintosh: via-pmu and via-cuda need RTC_LIB

Fix build when RTC_LIB is not set/enabled.
Eliminates these build errors:

m68k-linux-ld: drivers/macintosh/via-pmu.o: in function `pmu_set_rtc_time':
drivers/macintosh/via-pmu.c:1769: undefined reference to `rtc_tm_to_time64'
m68k-linux-ld: drivers/macintosh/via-cuda.o: in function `cuda_set_rtc_time':
drivers/macintosh/via-cuda.c:797: undefined reference to `rtc_tm_to_time64'
