Subject: [PATCH] main: reset the terminal properly on SIGINT,SIGTERM

This commit fixes the issue that on `CTRL-C` (SIGINT) the progress
is not properly cleared. It also catches SIGTERM for good measure.

No test right now as this is hard to test automatically :/

Closes: https://github.com/osbuild/image-builder-cli/issues/123
