Fix AES-CTR compatibility issue in ipsec
r361390 decreased blocksize of AES-CTR from 16 to 1.
Because of that ESP payload is no longer aligned to 16 bytes
before being encrypted and sent.
This is a good change since RFC3686 specifies that the last block
doesn't need to be aligned.
Since FreeBSD before r361390 couldn't decrypt partial blocks encrypted
with AES-CTR we need to enforce 16 byte alignment in order to preserve
compatibility.
Add a sysctl(on by default) to control it.
