Add a configuration option for specifying location of the qemu modules directory, defaulting to /usr/lib64/qemu. Then use this location to check for changes in the directory, indicating that a qemu module has changed and capabilities need to be reprobed.

This is a mildly tested impl of the idea discussed here (and elsewhere in the thread)

I've checked that both system and session caches are updated when a qemu modules package is updated. I'll do some more testing but wanted to send the patch for early comments. Testing in other environments would be much appreciated. Thanks!
