[PATCH backup 2/2] api: time: rename read_etc_localtime

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

The function tries to get the timezone from timedatectl and fallbacks to
/etc/localtime, so we rename it to get_timezone.

Notes:
    Whether timedatectl uses /etc/localtime is an implementation detail, but
    please feel free to drop this commit if it does not add much.
