base: libs_allocators test fails with glib 2.76.1

• Ubuntu 23.04
• glib 2.76.1
• gst-plugins-base 1.22.1

The libs_allocators build test is failing on Ubuntu 23.04. I was able to duplicate this issue on Debian 12 if I installed glib 2.76.1 there.

I suspect that this was triggered by glib's removal of the slice allocator which has uncovered use-after-free issues in several projects.

We only fail the build for test failures on amd64 and arm64. Somehow the build test passes on arm64.
