tests: Fix EAP-SIM/AKA protocol tests to use full header

Couple of the EAP-SIM/AKA protocol test cases were leaving out the
Reserved field. This was not intentional since these test cases were
targeting a specific Subtype processing instead of verifying truncated
header case (which is covered separately). Add the Reserved field to
allow the implementation to add an explicit, earlier check for this.
