test_cpu_times fails with Linux >=3.10

[GoogleCodeExporter]

======================================================================
ERROR: test_cpu_times (_linux.LinuxSpecificTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/tmp/psutil/test/_linux.py", line 123, in test_cpu_times
    kernel_ver = re.findall('\d.\d.\d', os.uname()[2])[0]
IndexError: list index out of range

----------------------------------------------------------------------

os.uname()[2] is a string starting with e.g. '3.10.9'.

>>> re.findall('\d.\d.\d', '3.10.9')
[]

Truncation of version number is also possible for older Linux versions:

>>> re.findall('\d.\d.\d', '3.9.11')
['3.9.1']

Actually '.' also should be escaped:
