ttcn3-bsc-test-io_uring: limit jenkins nodes again

Run this job only on jenkins nodes with a linux kernel of 6.1.x or
higher. The io_uring implementation consumes a lot more memory on e.g.
the 5.10.x kernel of host2, which causes osmo-bsc to run out of memory
in other places:

<0002> system_information.c:1641 bts 0: Error while generating SI4: Cannot allocate memory (-12)
<0002> bts_trx.c:505 Cannot generate SI4 for BTS 0: error <Cannot allocate memory>, most likely a problem with neighbor cell list generation

ansible/setup-jenkins: install rsync

After recent refactoring of the gerrit-binpkgs job, rsync is now
requried on the jenkins nodes. It was installed on the ones where I
tested, but not on all of them.

Fixes: b2e12851 ("OBS: move gerrit-binpkgs logic to separate script")

jobs: gerrit: build osmo-pcap + dep for centos7

We are about to remove the rpm spec files for almost all Osmocom git
repositories. The only two git repositories where we still need them,
because we have a customer using them on centos 7, are libosmocore and
osmo-pcap (SYS#6760). Add CI to ensure that these still build fine, and
that we don't remove these by mistake.
