chore(net): raise the TCP socket buffer max to 8 MiB

Browse Source 
- host sysctl (20-network.sh): tcp_rmem/tcp_wmem max, rmem_max and
  wmem_max all go from 4194304 to 8388608
- image builds (50/60/70/80/90 + eol-debian11): tcp_rmem/tcp_wmem max
  bumped the same way
- autotune defaults (262144) and the min values are untouched
