Changed paths: M libknet/tests/api_knet_send_crypto.c M libknet/threads_pmtud.c

Log Message: ----------- [pmtud] break on loop when using crypto

under certain circumstances, when crypto is enabled, pMTUD will continue sending a packet of the same size over and over just at the MTU boundary.

In case we are sending the same packet twice (due to crypto alignment and such), it means we cannot make any more progress and we need to take that size as ultimate MTU.

Fixes: https://github.com/kronosnet/kronosnet/issues/241

Also change default test parameters to easily trigger the issue in case of regression. Tested using ifconfig lo mtu 65520.
