[PR] Security clothing vendor cleanup

[Ikea]

Please do not remove the Hawaiian shirt from the security vendor. Thanks

I attempted to sprite a red and black hawaii shirt initially intended to go with this pr before putting it on hold. I'll likely pick back up those attempts and put that back into the pr. I like the idea of a laid back casual sec uniform however it pains me whenever I see an antag try to do something bold before being immediately batoned by a plainclothes secoff therefore I think the hawaii shirts should be identifiably security.
