py3: use pycompat.bytestr so that we don't get ascii values
This fixes `hg files 'set:(**.py)'` which makes test-check-py3-compat.t able to
run on Python 3. So if you now do `python3 ./run-tests.py
test-check-py3-compat`, the test will actually run.

Utility for inspecting files in various ways.
This tool is like the collection of tools found in a unix environment but are
cross platform and stable and suitable for our needs in the test suite.
This can be used instead of tools like:
[
dd
find
head
hexdump
ls
md5sum
readlink
sha1sum
stat
tail
test
