python-2.7.3:remove BOM insertion code

Backport patch from:
https://hg.python.org/cpython/rev/af46a001d5ec

SysLogHandler converts message to utf8 and adds BOM, supposedly
to conform with RFC5424, but the implementation is broken:
the RFC specifies that the BOM should prefix only unstructured
message part, but current Python implementation puts it in the
middle of structured part, thus confusing RFC-compliant receivers.
