run-tests: fix escapes with conditions

Before this fix, escapes with conditions in tests failed like this on Python 3:

   $ $PYTHON -c 'from mercurial.utils.procutil import stdout; stdout.write(b"\xff")'
-  \xff (no-eol) (esc) (true !)
+  \xff (no-eol) (esc)

The unicode_escape encoding decodes br'\xff' to u'\xff'. To convert the first
256 code points to bytes with the same ordinal, the latin-1 encoding must be
used.

Escapes without conditions already worked before on Python 3, but not through
`el == l` a few lines below the changed line in run-tests.py. I didn’t
investigate further.

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
