Client: map keyboard mapping privately

Browse Source 
We are never going to write back changes into the compositor's keymap,
so there is no reason to have support for writing back to the
compositor.

V7 of the spec says:
"From version 7 onwards, the fd must be mapped with MAP_PRIVATE by the
recipient, as MAP_SHARED may fail."

Whilst we don't support v7 yet it is harmless to change this early.
