remove implication legwear_under_shorts -> pantyhose
pantyhose_under_shorts was aliased to legwear_under_shorts in topic #15698. However, nobody remembered to also remove the pantyhose implication created in topic #14123.
Since pantyhose is not the only type of legwear this tag could apply to (ex. leggings), this implication should be removed and the posts gardened.
