test: enable legacy support in version compatibility test

Browse Source 
Summary:
The version compatibility test needs to decode legacy frames (v0.5.x - v0.7.x) to verify cross-version interoperability. Since legacy support is now disabled by default (v1.6.0), head must be built with ZSTD_LEGACY_SUPPORT=5 for this test.

Test Plan:
Run `python3 tests/test-zstd-versions.py` to verify cross-version compatibility testing works correctly.
