[physfs] [patch] pkg-config support

[Jonas Kulla]

Hi everyone,

With my limited cmake knowledge, I took a shot at implementing proper
pkg-config support. Not
sure about conventions on attaching patches, so I'll just inline it in case
anyone wants to comment
on parts of it.

I guess the Right Way to Do It™ would be to name the package "physfs-1";
this all really depends
on how soon Ryan intends on breaking the API (when it would become
"physfs-2"). Otherwise,
just plain "physfs.pc" is nice and simple.
