chromium: fix vulkan linking

sengir · sengir · commit c714a76c0427 · 2023-02-15T23:12:52.000-07:00
libvulkan is dlopen'd but is missing from the linker search path. We probably should be using the libvulkan (and libGLESv2) provided by chromium, but using vulkan-loader's libvulkan.so.1 is a tried-and-true workaround. Fixes #150398.
