hidapi: look for the unsuffixed libhidapi.so

FreeBSD's comms/hidapi installs the library as libhidapi.so /
libhidapi.so.0, without a backend suffix. None of the existing candidate
names match it, so LoadLibrary exhausts the list and the module raises
ImportError at import time, making Solaar unusable there.
