Optimize IPsec MTU calculation. Now also tested with beet mode.
[XFRM]: Optimize MTU calculation
Replace the probing based MTU estimation, which usually takes 2-3 iterations
to find a fitting value and may underestimate the MTU, by an exact calculation.
Also fix underestimation of the XFRM

Tested with IPv4 and I
tunnel and transport mode. Beet mode
is untested since no keying daemon seems to support it.
