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

The 'Etc/UTC' timezone does not have a definite 2-letter country code
assigned. 'xx' was choosen on the basis that this hopefully will never
be assigned to any real country in the future, but a small collision
check won't hurt either.

This also means it does not have an entry in either the ISO-codes
definition file nor the zoneinfo table, thus needing to define it

Using just 'UTC' as timezone (name) also matches what PVE/PMG/PBS do in
their UI.

Some bike-shedding: If there is a better suggestion on what country code
to choose, I'll happily change it.

Also, although the correct timezone name is 'Etc/UTC', I chose 'UTC' as
"country name" to display in the installer to make it easier to find for
users, as they probably will just type 'UTC' in there at first, rather
than 'Etc'.
