fff-network: Remove sysctls that depend on disabled kernel features

Some sysctls currently are completely useless, as they only exist if
specific kernel configurations are enabled, which we have not.

To hide the error message and prevent them from interfering
unintentionally, if new kernel configurations are activated in the
future, they are removed.

Fixes: #42 (gitea)
