py3: create built in exceptions with str type messages in win32.py
I hit an IOError in unlink() in test-pathconflicts-basic.t, that then crashed as
it was handled:
File "mercurial\dispatch.py", line 359, in _runcatch
return _callcatch(ui, _runcatchfunc)
File "mercurial\dispatch.py", line 367, in _callcatch
return scmutil.callcatch(ui, func)
File "mercurial\scmutil.py", line 252, in callcatch
ui.error(_("abort: %s\n") % encoding.strtolocal(inst.strerror))
File "mercurial\encoding.py", line 205, in unitolocal
return tolocal(u.encode('utf-8'))
AttributeError: 'bytes' object has no attribute 'encode'
