[parisc-linux] Missing extern's in keyboard.h

[John David Anglin]

The following was noticed in the hunt for undefined common variables.
A number of extern's are missing in keyboard.h.  As a result, keyboard.h
actually defines the variables instead of just prototyping them.  The
initialization of them should be in keyboard.c.
