[OE-core] [PATCH V2 1/6] libssp-nonshared: Add recipe

[Burton, Ross]

build-appliance is failing at SDK creation time:

 Problem: package packagegroup-self-hosted-1.0-r13.0.noarch requires
packagegroup-self-hosted-sdk, but none of the providers can be
installed
  - conflicting requests
  - nothing provides libssp-dev needed by
packagegroup-self-hosted-sdk-1.0-r13.0.noarch
