hwdb: Add mapping for special keys on compaq ku 0133 keyboards

The compaq ku 0133 keyboard has 8 special keys at the top:

3 of these use standard HID usage codes from the consumer page, the 5
others use part of the reserved 0x07 - 0x1f range.

This commit adds mapping for this keyboard for these reserved codes, making
the other 5 keys work.

man: make udev.event-timeout more visible

Evidently some people had trouble finding it in the documentation.
