[PATCH] git-ci: use pylint to analyze the git-p4 code

[Viet Hung Tran <viethtran1620@xxxxxxxxx>]

Add a new job named Pylint to .travis.yml in order to analyze git-p4 Python code.
Although Travis CI have yet to implement continuous integration for multiple
languages. Python package can be installed using apt packages. From there, pylint can be
installed using pip and used to analyze git-p4.py file.
