Fix math cross-platform determinism (Jondolf#145)

Enables the libm feature for glam to support cross-platform deterministic math when enhanced-determinism is enabled.

This makes the snapshots produced by the cross-platform determinism test consistent across operating systems. The test is very simple however, so there might still be other determinism issues.
