ci: set FORCE_UNSAFE_CONFIGURE=1

The newer version of Buildroot recently selected in the OP-TEE manifest
[1] does not allow building as root by default (apparently this is not
a Buildroot policy but rather defined in some packages included in
Buildroot). While this makes sense in general, we could not care less in
a CI container. Therefore set the appropriate environment variable to
bypass this check. We could as well change the Docker image to build as
a non-root user but let's just pick the easiest way for now.
