msc: also execute evil USSD tests for -latest

osmo-msc v1.14.0 is out, so we can safely execute these tests.

testenv: use separate cache dirs per distro

testenv: init podman: add --distro arg

Allow building the podman image for another distribution. This was
mostly implemented already, but due to the missing --distro argument for
"./testenv.py init podman" it could not be used yet.

testenv: debian 13: fix installing libgcc

Use a wildcard to install the proper libgcc-*-dev package (libgcc-11-dev
for debian bookworm, libgcc-13-dev for trixie).

testenv: debian 13: fix installing eclipse-titan

Use the current debian version instead of hardcoding Debian_12.

testenv: check for --distro without --podman

The --distro option only makes sense with --podman, complain if it is
used without --podman.

testenv: check value of --distro early

Make sure that the value for --distro is supported early on, instead of
only checking it if --binary-repo is set while trying to add the binary
repository.

testenv: enable_binary_repo: configure apt pin

Add an apt-pin to ensure packages from the Osmocom repositories get
preferred over Debian's packages. I just ran into this with osmo-mgw,
where we have 1.4.0 in osmocom:latest and Debian 13 has 1.14.0+dfsg1-2,
which counts as higher version. This results in the wrong package being
selected, and also in an error later on when trying to install related
debug packages from our repository:

  The following packages have unmet dependencies:
   osmo-mgw-dbgsym : Depends: osmo-mgw (= 1.14.0) but 1.14.0+dfsg1-2 is to be installed

testenv: qemu: ignore builtin modules

In debian 13, the virtio_pci kernel module is now builtin. Adjust the
code paths that add kernel modules to the initramfs and load them to
ignore builtin modules.

This fixes the ttcn3-ggsn-test-kernel-latest job job, which currently
fails with:
