Add test for multiple SPs with the same UUID

Add a new test SP which is used to test when multiple SPs have
the same FF-A UUID. This change carries the following modifications to
the spm-test deployments:
  - introduce a new UUID which identifies the SP binary (like a file
    name)
  - ensure the binary UUID is used in output file names if set in the
    opteesp deployments
  - adds a new deployment to have two SPs with matching FF-A UUID
  - refactor tests to check if SPMC allows discovering SPs with matching
    FF-A UUID.
