net-vpn/libreswan: set INITSYSTEM correctly

INITSYSTEM was hardcoded to always be openrc. This was ignored in
libreswan 3.x where runtime detection was used, but in 4.x the
INITSYSTEM is hardcoded in the setup script at installation time. Set
INITSYSTEM based on the systemd USE flag instead.

Closes: https://bugs.gentoo.org/756121
