FindBZip2: Check BZIP2_NEED_PREFIX with real prototype

Browse Source 
Run our check for the '_' prefix using a bzip2 API function as declared
with a prototype in the real header file.  This is needed in case the
function is provided in a DLL import library where the symbol name may
not match without proper markup from the header.
