make: add a target for building pyoxidizer tests on macOS
The resources seem to be embedded inside the binary, but for some reasons they
aren't read there. And since they are embedded, they aren't staged by the build
in the `lib` directory like on Windows. So copy them from the repo. We can
figure out what's going wrong later.

# This extension enables removal of file content at a given revision,

# integrity.
"""erase file content at a given revision
The censor command instructs Mercurial to erase all content of a file at a given
revision *without updating the changeset hash.* This allows existing history to
remain valid while preventing future clones/pulls from receiving the erased
data.
Typical uses for censor are due to security or legal requirements, including::
* Passwords, private keys, cryptographic material
* Licensed data/code/libraries for which the license has expired
* Personally Identifiable Information or other private data
Censored nodes can interrupt mercurial's typical operation whenever the excised
data needs to be materialized. Some commands, like ``hg cat``/``hg revert``,
simply fail when asked to produce censored data. Others, like ``hg verify`` and
``hg update``, must be capable of tolerating censored data to continue to
function in a meaningful way. Such commands only tolerate censored file
revisions if they are allowed by the "censor.policy=ignore" config option.
A few informative commands such as ``hg grep`` will unconditionally
ignore censored data and merely report that it was encountered.
