Specify the encoding explicitly

If you try to compile intel-gpu-tools 1.7 in the C locale, where the default encoding is ASCII, you'll get this error:

make[5]: Entering directory '/src/xorg/intel-gpu-tools/work/intel-gpu-tools-1.7/
debugger/system_routine'
./pre_cpp.py ./sr.g4a > sr.cpp.tmp && mv sr.cpp.tmp sr.cpp
Traceback (most recent call last):
  File "./pre_cpp.py", line 38, in <module>
    lines = file.readlines()
  File "/gar/lib/python3.4/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 16: ordinal not in range(128)

That's because pre_cpp.py is a Python 3 program, and it's just called open() on the file, which contains a UTF-8-encoded copyright symbol, without specifying an encoding. In that case, Python 3 defaults to whatever the locale's encoding is, so this'll work if your locale's encoding is UTF-8, but will either crash or misinterpret the file if not.

One fix is to explicitly specify the encoding when opening the file. Patch attached.
