package/x11r7/xwayland: xlib_libxshmfence is mandatory

xlib_libxshmfence is mandatory, not optional, since the addition of the
package in commit 05c3177493aa8447d5cb568c8c13e0c09eded18b:

../miext/sync/misyncshm.c:36:10: fatal error: X11/xshmfence.h: No such file or directory
   36 | #include <X11/xshmfence.h>
      |          ^~~~~~~~~~~~~~~~~
