[hwclock] Be more lenient.

Browse Source 
Patch by Gabriel C. (@abucodonosor).

 - use libcalamares functions
 - no need to copy /etc/adjtime over we can run hwclock in chroot
   since we have /proc , /sys , /dev , /run/* already bind mounted.
 - added RTC and ISA probing methode ( see issue #873)
    - we probe default from /dev/rtc* ,
    - fall back to ISA
    - still doesn't work we just print a BIOS/Kernel BUG message and continue
- NOTE: issue #873 is about broken ArchLinux kernel config but there
  are HP boxes with real RTC problems no matter what kernel config
  is used so let us be nice and don't error out..

FIXES #873
