Bug 258269: graphics/libglvnd: update to 1.3.4
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258269



--- Description ---
- See URL for upstream changes
- Optionally required by https://github.com/swaywm/wlroots/commit/101b9a193d91
and https://github.com/swaywm/wlroots/commit/3cf2535c2339
- EGL headers update is slightly risky but not as much as
graphics/mesa-dri/files/patch-compat-include-guards removal was.

Builds fine (poudriere testport):
- 11.4 amd64/i386
- 12.2 aarch64/amd64/i386
- 13.0 amd64/i386
- 14.0 aarch64/amd64/armv6/armv7/i386
