What Does This PR Do

Adjusts the following earwears to fit monitor heads:

/obj/item/clothing/ears/earmuffs ("earmuffs" in earmuffs.dm)
/obj/item/clothing/ears/headphones ("headphones0"/"headphones1" in headphones.dm)
/obj/item/radio/headset ("headset" in radio/headset.dm)
/obj/item/radio/headset/alt ("com_headset_alt" in radio/headset.dm)
/obj/item/radio/headset/headset_sec/alt ("sec_headset_alt" in radio/headset.dm)
/obj/item/radio/headset/syndicate/alt ("syndie_headset" in radio/headset.dm)
/obj/item/radio/headset/soviet ("soviet_headset" in radio/headset.dm)
/obj/item/radio/headset/abductor ("abductor_headset" in abduction_gar.dm)

Why It's Good For The Game

It's nice when your headphones sit around your head instead of clipping into your head.

Images of changes

All earwears.

Small test that the change only affects monitor heads.

Testing

Compiled, hosted, dressed monitor head characters, turned on music notes of headsphones.
