py3: replace os.pathsep with pycompat.ospathsep

os.pathsep returns unicode on Python 3. We already have pycompat.ospathsep
which return bytes on Python 3. This patch replaces all the occurrences of
os.pathsep in the codebase (excluding tests) to pycompat.ospathsep.

"""
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
  readlink.py
  md5sum.py
