Fix horns getting hidden in modsuits (#5891)

## About The Pull Request

Couple things going on here but basically boils down to the
`/datum/bodypart_overlay/mutant/horns/can_draw_on_bodypart` proc in
`_visual_organs.dm` blocking horns if outfit has `HIDEHAIR` flagged
which mods do, this is all fine and dandy but we have a specific
carve-out for mods because of the hardlight overlays they add, problem
is that the latter check was taking precedence over the carve-out
(`is_deely_bopper_hidden`). I commented out this check because
`is_deely_bopper_hidden` does everything it does and more, so we don't
need it. Also deleted a redundant skyrat override on
`/datum/bodypart_overlay/mutant/horns/can_draw_on_bodypart` because the
parent `/datum/bodypart_overlay/mutant/can_draw_on_bodypart` override
does the same thing.
