time64.inc: Add warnings exclusion for known toolchain problems for now

Fixing our infrastructure to show warnings for nativesdk packages resulted
in some issues with 32 bit toolchains and 32 bit time becoming clear.

For now, add INSANE_SKIP entries for these which effectively documents
the issue and allows us to at least start running the tests in the
infrastructure.

Over time we will need to try and fix these if upstream doesn't.
