The `pylint-3` executable is provided by the python3-pylint rpm
package on Fedora.
For Debian the equivalent is `pylint3`.
On Arch Linux the default version of Python is 3.

Pylint lints for the version of Python it is running. Instead of
spawning an executable, import the `pylint.lint` module and call
`Run()`.
