Resolve relative symlink of /etc/localtime This fixes wrong detection of system timezone under certain circumstances.
Example: in Fedora 20, the environment is a follows: a) /etc/localtime symlinks --> ../usr/share/zoneinfo/Europe/Zurich b) /usr/share/zoneinfo contains files with more than 1 hardlink. In example, Europe/Zurich and Europe/Vaduz share the same i-node. - system_timezone_read_etc_localtime_softlink() because the link is relative. - The next algorithms fail because the targeted files do not exist. - system_timezone_read_etc_localtime_hardlink() succeeds, but finds Europe/Vaduz before Europe/Zurich. Thus the detected system timezone is wrong. By resolving a relative /etc/localtime symlink, this patch leads algorithm system_timezone_read_etc_localtime_softlink() to success and therefore proper detection of system timezone.
