Python 3: raster/r.in.poly/testsuite/test_rinpoly.py is broken

[pmav99]

This is the error:

=====================================================================
ERROR: testLabels (__main__.TestRInPoly)
Test type of resulting map
----------------------------------------------------------------------
Traceback (most recent call last):
  File "raster/r.in.poly/testsuite/test_rinpoly.py", line 103, in testLabels
    self.tmpFile.write(input1)
  File "/usr/lib/python3.7/tempfile.py", line 481, in func_wrapper
    return func(*args, **kwargs)
TypeError: a bytes-like object is required, not 'str'

The problems is that NamedTemporaryFiles are opened in binary mode by default:

• ​https://docs.python.org/2/library/tempfile.html#tempfile.NamedTemporaryFile
• ​https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile

This is the git diff for the fix:

Should work as it is in Python2 too.
