Address "make dudect more portable?"

[itzmeanjan]

Adds support for running dudect -based constant-time tests on more targets i.e. aarch64 (running Linux kernel), Apple Silicon and more non-x86_64 targets.

Partially addresses https://github.com/oreparaz/dudect/issues/33.

This is great @itzmeanjan . Thank you. Can you please list here the targets in which you tested it? (Maybe the test should be run test.py?)

I'll also test in a bunch of hardware and report back here.
