The helper mptcp_lib_verify_listener_events() will be added latter in
mptcp_lib.sh, and be used by mptcp_join.sh and userspace_pm.sh. The
former prints colored output while the latter is not. It makes sense
to unify them.

Use mptcp_lib_print_ok(), _warn() and _err() to instead print_results()
in test_pass(), _skip() and _fail(), and use mptcp_lib_print_info() to
instead _printf() in print_title() to print test results with colors
in userspace_pm.sh.
