add option to disable setting the system clock on boot for linux systems

Browse Source 
This commit adds the clock_hctosys option which is used to skip setting
the system clock on boot and can be used with a modern linux kernel
which has the CONFIG_RTC_HCTOSYS option set to y.
I would like to thank Dimitris Mandalidis for the report and for the
patch to baselayout-1 on which my changes to openrc are based.
