Subject: [PATCH] Gallium: Fix shared memory segment leak

Commit abe6d750e58d371624de75f4bad365c61e0196c1 caused shared memory
segments to be leaked. We need to mark shared memory segments for
deletion upon construction.

Fixes: abe6d750e5 xlib: fix glXDestroyContext in Gallium frontends
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/9425
