x11vnc: fix CAPS_LOCK issues
Currently, pressing CAPS_LOCK on the viewer changes the lock state on
the server and the key will not change the case.
To fix this, use -skip_lockkeys option to ignore all Caps_Lock,
Shift_Lock, Num_Lock, Scroll_Lock keysyms received from viewers, in
order to leave the lock state on the server side unchanged. However, the
keys will appear correctly on the remote side.
