[PATCH 01/16] tests/qapi-schema: Fix test 'QAPI rST doc'

[Markus Armbruster <armbru@redhat.com>]

The test compares Sphinx plain-text output against a golden reference.
To work on Windows hosts, it filters out carriage returns in both
files.  Unfortunately, the filter doesn't work: it creates an empty
file.  Comparing empty files always succeeds.

Fix the filter, and update the golden reference to current Sphinx
output.
