Fix TC_SWDIAG_3_1.yaml test case on Linux (#15215)

* Fix TC_SWDIAG_3_1.yaml test case on Linux

- The test case previously expected used/free heap value of 0.
- Now the SDK is implementing heap read properly from Linux when
  built with glibc. This made the code return a real value
  that fails the test.
- Overall, there is no "value" value for heap, we just need
  a value. The explicit value was replaced with expecting
  a returned value back.
