libnm/tests: include "nm-default.h" for "libnm-core/tests/nm-core-tests-enum-types.c"

With glib2-2.67.0-1.fc34.x86_64.rpm, clang-11.0.0-2.fc34.x86_64.rpm, the
generated code emits a compiler warning:

We could pass "-Wincompatible-pointer-types-discards-qualifiers" as CFLAGS
when building this file. However, we have a workaround in our "nm-glib-aux/nm-glib.h",
so we can instead include "nm-default.h". At first glance, that might look like
the less preferable solution. However, this file is only there for unit tests,
and we also include "nm-default.h" for other sources that are generated with
"glib-mkenums". So, doing it also for our tests becomes the preferable solution.
