setkey: MFC: load ipsec.ko automatically

If setkey(8) is used without ipsec.ko loaded beforehand,
its attempt to install SA/SPD into the kernel results in cryptic
EINVAL error code.

Let it be a bit more user-friendly and try to load ipsec.ko
automatically if it is not loaded, just like ifconfig(8) does it
for modules it needs.
