#2375: make tests work under a non-ASCII path

--------------------------------+---------------------------
 Currently when I run tests for a checkout of Tahoe-LAFS (at
 [/9ac392802b6034aefd4c742ea9dd02813f4667d9/trunk]) on Linux under a
 directory with "€" in its name, there are many test failures:
 {{{
 FAILED (skips=5, expectedFailures=3, failures=2, errors=79,
 successes=1075)
 }}}
 After working around a shallow problem with `os.statvfs` not accepting a
 Unicode path, this becomes:
 {{{
 FAILED (skips=5, expectedFailures=3, failures=2, errors=71,
 successes=1083)
 }}}

 Most of the remaining errors have this traceback:
 {{{
