Subject: [PATCH] style: Use command -v instead of which for availability
 checks

rc.d/anyenv, rc.d/screen, aliases.d/mc, and rc.d/startx were the last
holdouts still using `which` to check tool availability. Every other
file in rc.d/* already uses `command -v`, which doesn't depend on an
external binary being installed.
