test/crypto: add fragmented packet case

Add fragmented plain packet test case in combined mode.
The test case leverages combined mode framework to generate
IPsec packet from a fragment and verify that headers are formed
correctly. The IPsec packet would be decapsulated and the plain
packet is compared against the original packet.
