When doing local testing of AOT configurations I need to
manually override use-elf property to shorten cycle time.
Currently this can only be done by editing test_matrix.json,
this CL adds a capability to achieve the same by defining
TEST_CONFIGURATION_OVERRIDES environment variable.
I also fix some incorrect checking code which never triggered before:
if you try (via CLI flag) to override an option which is already
defined by a selected named configuration you should get an error.
