Fixed bug 2149 - Don't search for libusbhid except on BSD

Joseph Carter

There's a whole set of configure tests for BSD's libusbhid, and they only matter on BSD.  However, if you have the library on Linux, it gets pulled in as library bloat.  And it's bloat of the highest order since not a single function call to the library is ever made unless you're on a *BSD.
