kernel: remove support for kernel 4.19

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

-Subject: [PATCH] netfilter: nf_flow_table: fix up ct state of flows after
- timeout
-
-If a connection simply times out instead of being torn down, it is left
-active with a long timeout. Fix this by calling flow_offload_fixup_ct_state
-here as well.
