hwdb: Fix F12 mapping on the Logitech Internet Navigator

Many Logitech keyboards have the following special functions on F9-F12:
F9: file-browser F10: document-browser F11: image-browser F12:
music-browser. These should be bound to:

 #define KEY_FILE               144     /* AL Local Machine Browser */
 #define KEY_DOCUMENTS          235
 #define KEY_IMAGES           0x1ba     /* AL Image Browser */
 #define KEY_AUDIO            0x188     /* AL Audio Browser */

This commit fixes the wrong binding of F12 to KEY_SOUND (which
translates to XF86AudioPreset) and removes the ?? comments from
both F11 and F12.
