Mark global wayland constant extern

Browse Source 
Without `extern`, the changed lines are not declarations,
but "tentative definitions"
(according to GCC man page, option `-fcommon`).
When specified in a header file
that is included in more than one `.c` file,
these result in linking failure unless `-fcommon` is specified.

GCC 10 changed the default from `-fcommon` to `-fno-common`,
and as such the previous code no longer links properly.

With `extern`, these lines are considered declarations,
and the linking proceeds successfully.
