This will allow us to control the value from test plans, in particular
for disabling at least some unexpected message checks for reverse
dependency testing. We don't want to disable unexpected messages
in general for fmf, as we are looking for exactly these in e.g.
selinux-policy reverse dependency tests.
Move from `su` to `runtest`, as with the former it's impossible to plumb
through variables with non-trivial characters, as they cannot be quoted.

Cockpit recently changed to an ESM build system [1]. Bump
COCKPIT_REPO_COMMIT to that and follow suit.
This does not work with old node.js 10 any more which is still the
default in RHEL 8. Install the newer version 16 instead.

Copy and adjust the browser.sh and run-test.sh scripts from
cockpit-podman, which we have used in Fedora/RHEL dist-git gating and
packit tests for a while.
