[PULL v5 15/44] tests/docker: remove FEATURES env var from templates

["Alex Bennée" <alex.bennee@linaro.org>]

From: Daniel P. Berrangé <berrange@redhat.com>

In preparation for switching to auto-generated dockerfiles, remove the
FEATURES env variable. The equivalent functionality can be achieved in
most cases by just looking for existance of a binary.

The cases which don't correspond to binaries are simply dropped because
configure/meson will probe for any requested feature anyway.
