STYLE fix the way we call pylint
I had these two errors related to pylint version upgrade. I think this fixes it.
************* Module /home/trentesauxh/dev/iota2/iota2/.pylintrc
iota2/.pylintrc:1:0: R0022: Useless option value for '--disable', 'R0201' was moved to an optional extension, see https://pylint.pycqa.org/en/latest/whatsnew/2/2.14/summary.html#removed-checkers. (useless-option-value)
************* Module Command line
Command line:1:0: W0012: Unknown option value for '-d', expected a valid pylint message and got 'isable=C0415' (unknown-option-value)
