bindings: python: tests: fix checking the kernel version

Kernel release candidate version strings seem to not be working
correctly with python's version.parse() function. Split the string
retrieved with os.uname().release using '-' as delimiter and pass
only the first part - 'major.minor.release' - to version.parse().
