tests: write out file using bytes I/O

The encoding of sys.stdout varies between Python versions. So
using a one-liner to write a file from a Unicode string is not
deterministic.

This commit writes out the file using bytes I/O to ensure we
have exactly the bytes we want in the file.

This change fixes a test failure in Python 3.5/3.6.
