Changes

scripts/kernel/linux-shallow-clone: new script

Add a script that maintains a linux repository in one place on jenkins
nodes, so we need less git clones from git.kernel.org and less disk
space. All jobs that need a kernel tree can now clone the relevant
branch directly from the jenkins node.

Follow up patches will add a jenkins job that runs the script daily and
adjust the existing jobs to make use of this instead of doing their own
clones.

Currently this script produces a 396M bare git repository.

repo-install-test: test osmo-pfcp-tool in latest

osmo-pfcp-tool is available in latest for quite some time now, so adjust
the check.

repo-install-test: debian 10: osmo-gbproxy only

The debian 10 repository has been officially disabled:
https://osmocom.org/news/308

However we just re-enabled a subset of the packages, osmo-gbproxy +
dependencies, because currently they are relevant for a customer. Adjust
the repo-install-test to deal with this subset of packages for debian 10
to fix that it is currently failing.

I have verified that repo-install-test works with this change for debian
10, 11 and 12. It currently doesn't run for debian 13 yet (OS#6934).

Osmocom_OBS_sync: fix failing on new scmsync tag

The openSUSE OBS instance has added an scmsync tag to their debian 13
meta config:

  <scmsync>https://src.opensuse.org/obs/debian#13</scmsync>

This feature is not supported by the stable OBS version yet (they run
current master), and so the sync fails with:

  project validation error: 6:0: ERROR: Element project has extra content: scmsync

Remove the tag to fix this.
