Codespell dictionary path is no longer absolute

Codespell dictionary path is no longer absolute

[Dwaipayan Ray]

A year ago, the codespell dictionary was moved from
/usr/share/codespell/dictionary.txt to data/dictionary.txt under
the codespell_lib installation directory.

checkpatch.pl still has the default codespell path as
/usr/share/codespell/dictionary.txt.
Any new installations will now also need to specify --codespellfile
option along with --codespell.

Can auto detection of the dictionary path be enabled with something
like this?

Maybe, but it doesn't work with python2

And it's likely better to do as few things in python as possible
so maybe ditch the op.join and use perl instead

	if (! -e "$codespellfile" && which("python") ne "" &&
	    `python -c "import sys; print(sys.version_info.major)"` >= "3") {
		$codespellfile = dirname(`python -c "import codespell_lib; print(codespell_lib.__file__);"`) . "/data/dictionary.txt";
	}
