Jonas Dreßler 988da215c8 wayland/keyboard: Use MetaAnonymousFile to share keymap files
Since protocol version 7 clients must use MAP_PRIVATE to map the keymap
fd, that means we can use memfd_create() to create the fd by using
meta_anonymous_file_open_fd() with META_ANONYMOUS_FILE_MAPMODE_PRIVATE,
for older versions we use META_ANONYMOUS_FILE_MAPMODE_SHARED to be
compatibile with MAP_SHARED.

Pretty much all of this code was written for Weston by Sebastian Wick,
