.gitignore: ignore Python compiled bytecode

.gitignore: ignore Python compiled bytecode

While the building system doesn't create any Python JIT bytecode,
if one manually runs kernel-doc.py or get_abi.py, Python will,
by default, create a bytecode and store it under scripts/lib/*.

This is normal, and not controlled by the Kernel itself. So,
add *.pyc as an extension to be ignored.
