test: update libzstd_builds.sh for disabled legacy default

Browse Source 
Summary:
Updates the library build tests to reflect that legacy format support is now disabled by default. Also adds a new test case to verify that legacy support can still be explicitly enabled via ZSTD_LEGACY_SUPPORT=5.

Test Plan:
Run `bash tests/libzstd_builds.sh` on a Linux environment.
