kunit: string-stream-test: Avoid cast warning when testing gfp_t flags

Passing a gfp_t to KUNIT_EXPECT_EQ() causes a cast warning:

  lib/kunit/string-stream-test.c:73:9: sparse: sparse: incorrect type in
  initializer (different base types) expected long long right_value
  got restricted gfp_t const __right

Avoid this by testing stream->gfp for the expected value and passing the
boolean result of this comparison to KUNIT_EXPECT_TRUE(), as was already
done a few lines above in string_stream_managed_init_test().
