This isn't good enough, because it still picks "UCT" on a system with no
/etc/localtime and no TZ variable. Testing on HEAD as of 3da73d683 (on
FreeBSD, but it'll be the same anywhere else):

% ls -l /etc/*time*
ls: /etc/*time*: No such file or directory

% env -u TZ bin/initdb -D data -E UTF8 --no-locale
[...]
selecting default timezone ... UCT

We need to absolutely prefer UTC over UCT if both match.
