Stop checking for commands the package set guarantees

gum and ttfx ship in omarchy-base.packages and setfont comes with kbd, so
none of them needs a presence check — and every setfont call already
tolerates a failure anyway. btrfs-progs is in omarchy-other.packages and a
reset genuinely cannot proceed without it, so that one keeps its guard and
moves to the helper.
