ut_kvp: is not handling relative paths for loading

[Ulrond]

Goal:

• [] ut_kvp doesn't handle relative paths correctly and causes an asset

./bin/run.sh -p ./profiles/source/Source_AudioSettings.yaml 
...

hal_test: ... /ut-core/src/ut_kvp_profile.c:36: ut_kvp_profile_open: Assertion `result == UT_KVP_STATUS_SUCCESS' failed.
./bin/run.sh: line 24: 1116020 Aborted                 (core dumped) ./hal_test $@

ut-core just calls ut_kvp_open() therefore the issue is in this module.

    result = ut_kvp_open(gKVP_Instance, fileName);
    assert( result == UT_KVP_STATUS_SUCCESS );

Requirement:

• Relative paths for loading of files needs to be handled.
