[PATCH] test: only flag parse tests as little-endian-only in test-gvariant-message

[Amaan Qureshi <git@amaanq.com>]

The blanket `l_test_set_default_flags(L_TEST_FLAG_LITTLE_ENDIAN_ONLY)`
marks all gvariant-message tests as little-endian-only, but the build
and rewind tests work correctly on big-endian. This causes an XPASS
(unexpected pass) on big-endian systems, which autotools treats as a
test suite failure.

This commit applies the flag only to the three parse tests that compare
against hardcoded little-endian byte sequences.
