    tools/configure: Drop -lcrypto search
    
    This seems to be looking for a function MD5.  But nothing uses it.
    The build works fine if this is disabled and libcrypto is not
    installed.
    
    This check was first introduced in 68a3e1e87325 "[TOOLS] Add more
    checks for devel packages." in 2006.  At that time -lcrypto was used
    by tools/blktap/ and tools/vtpm_manager/, which are both gone now.
