Fix build error with configstore

CL I2c0895f8afbbb2947b62164acaf62a491c451dc0 made it necessary
to include android.hardware.configstore-utils as a shared library.
Was causing build error that looked like:
ninja: error:
'out/target/product/generic_x86_64/obj/HEADER_LIBRARIES/android.hardware.configstore-utils_intermediates/export_includes',
needed by
'out/target/product/generic_x86_64/obj/NATIVE_TESTS/EGL_test_intermediates/import_includes',
missing and no known rule to make it
23:25:54 ninja failed with: exit status 1
make: *** [run_soong_ui] Error 1

Happened in tests directory which doesn't get built by default.

Test: build opengl/tests
