[pve-devel] [PATCH v2 installer] fix #4430: add UTC timezone as option to installer

[Christoph Heiss <c.heiss@proxmox.com>]

Adds 'Etc/UTC' as option to the timezone selection, regardless of what
country is selected.

The 'Etc/' prefix needs to be stripped for the installation, as this
value is written to /etc/timezone. PVE/PMG/PBS already use 'UTC' without
the prefix, so avoid regressing them.

Would it be sensible to fix up the timezone change component in the UI
so that it uses 'Etc/UTC' (which is the canonical timezone name for UTC)
as well? As separate patch in the future, of course.
