Extend the RunCMake.set_property test with cases covering buildsystem
target properties:

* COMPILE_DEFINITIONS
* COMPILE_FEATURES
* COMPILE_OPTIONS
* INCLUDE_DIRECTORIES
* LINK_LIBRARIES
* SOURCES

Also test a non-buildsystem property to document the current difference
in behavior.  Refactor the existing LINK_LIBRARIES case to the same
more-extensive test as the rest.  Use the output generated by CMake 3.3
as the expected output for each test case.
