[larvacea]

Description of changes:

Update kernels to latest AL kernels available in the repositories.

Testing done:

Validate basic functionality through sonobuoy quick test:

The upstream configuration change to CONFIG_NF_FLOW_TABLE_PROCFS turns on netfilter flow table offload statistics in /proc/net/netfilter/nf_flowtable in the 5.15 kernel.

Kernel 5.15 dropped one patch that is no longer needed. Both kernels added 5 patches in the TLS component in networking.

I reran the sonobuoy tests. They still passed, and (even better news) I have the results:

22:30:56 Sonobuoy has completed. Use `sonobuoy retrieve` to get results.
