[rocprofiler-compute] Test env. vars. in rocprofiler-sdk backend (#2414)

* Test env. vars. in rocprofiler-sdk backend

* Improve rocprofiler-sdk backend test case to check for env. vars. and
  ensure we do not overwrite irrelevant env. vars.

* Remove unnecessary usage of ROCPROF_INDIVIDUAL_XCC_MODE env. var.

* Formatting fixes

* Test fixes

* Remove redundant code in tests

* Remove usage of utils_mod and use utils instead, this prevents
  duplicate imports
