pkg-cmake.mk: Set CMAKE_SYSTEM_PROCESSOR.

Browse Source 
This is rarely needed by packages, but convenient to have when it is.

[Thomas:
  - don't define ARM_VARIANT as this name is too global, use
    CMAKE_SYSTEM_PROCESSOR_ARM_VARIANT instead.
  - don't use ifndef, but a more traditional else clause, for the
    non-ARM cases.]
