[strongSwan] Explicit module loading on charon

Having two socket implementations is problematic and the daemon might
ignore the packet completely.

Are you using IKEv1, too? These are pluto specific options.

What's the reason for enabling the raw socket? Using the default is just
fine (socket-default if pluto disabled, socket-raw otherwise).

If you enforce socket-raw for some reasons, you should disable
socket-default.
