Always pass 9 parameters to tparm()

Some implementations like NetBSD have a non-variadic prototype of
tparm() requiring 9 explicit parameters. Therefore always make sure to
pass 9 parameters. Since other implementations uses a variadic prototype
it will work on them as well.

Inspired by how this solved in the portable version of tmux.

Spotted by Jenz Guenther in PR #216.
