[PATCH v2 26/30] tests/docker: update and flatten debian-loongarch-cross

[Alex Bennée]

Update to the latest stable Debian. While we are at it flatten into a
single dockerfile. We really don't need the rest of the stuff from the
QEMU base image just to compile test images. In this case it is a
binary distribution of the toolchain anyway.
