[ima-evm-utils PATCH v3 06/14] tests: Address issues raised by shellcheck SC2034

[Stefan Berger]

Address issues raised by shellcheck SC2034:
  "foo appears unused. Verify it or export it."

Export PKCS11_KEYURI in a separate statement to avoid the following
shellcheck issue:

  SC2155 (warning): Declare and assign separately to avoid masking
                    return values.
