Props: match the studio model name format

studiohdr_t::name is not "models/props/...". In this build it is the short
model name with Windows separators, e.g. "props_junk\wood_crate002a.mdl"
(the models/ prefix is stripped). Normalise the prefix/separators and match
props/, props\ and props_ (excluding the distant props_skybox set), so the
studio hooks actually recognise prop draws.
