noop-renderer: Remove volatile and use compiler attribute

Browse Source 
clang-13 complains about bitwise xor assigments like the following:

../libweston/noop-renderer.c:62:25: warning: variable 'unused' set but
not used [-Wunused-but-set-variable] volatile unsigned char unused = 0;

Use the __attribute__((unused)) instead.
