Update std doctests for android

This updates some doctests that fail to run on android. We will soon be
supporting cross-compiled doctests, and the `arm-android` job fails to
run these tests.

In summary:
- Android re-exports some traits from linux under a different path.
- Android doesn't seem to have common unix utilities like `true`,
  `false`, or `whoami`, so these are disabled.
