compat.quickjs-ng 0.17.0 on macOS and Windows (#582)

* compat.quickjs-ng 0.17.0 on macOS and Windows

The descriptor declared Linux only. Upstream builds the same four
sources with the same flags on all three platforms, and openmui's
TypeScript binding embeds the engine on every desktop. macOS needs
nothing more (libSystem has libm and pthreads). Windows adds
_CRT_SECURE_NO_WARNINGS, as upstream's CMake does for MSVC-ABI builds.

The test is no longer gated to Linux, so it now evaluates the same
JavaScript on macOS and Windows. Checked locally on x86_64-linux-gnu,
and for x86_64-windows-gnu under wine.
