Fix bogus test suite breakage on older Pythons:

* subversion/tests/clients/cmdline/log_tests.py
  (escape_control_chars): Use 1 and None as booleans, instead of
    True and False.  The latter two were introduced in Python
    2.2.1, but our tests claim only 2.0 or higher is required.
    See http://www.python.org/2.3/highlights.html [sic].

This was spotted thanks to Branko Čibej's breakage emails, see
http://subversion.tigris.org/servlets/ReadMsg?list=svn-breakage&msgNo=25019
for example.
