cli-tests/common.sh: remove argument count checks

These confuse the latest version of shellcheck into thinking that
functions which take no arguments actually take arguments, which
triggers a bunch of warnings like "Use func "$@" if function's $1 should
mean script's $1", which causes 'make lint' to fail.  These checks
aren't too useful, so just remove them.
