Call shmget() with permission 0600 instead of 0777
A security advisory (TALOS-2019-0857/CVE-2019-5068) found that
creating shared memory regions with permission mode 0777 could allow
any user to access that memory. Several Mesa drivers use shared-
memory XImages to implement back buffers for improved performance.
This path changes the shmget() calls to use 0600 (user r/w).
Tested with legacy Xlib driver and llvmpipe.
