Johannes Altmanninger a205225b4e lint.fish: properly handle -I and -D args for cppcheck
lint.fish receives arguments that contain multiple includes and defines.
As a result, we passed arguments like
"-I/usr/include -I$HOME/fish-shell/build -I/usr/include"
to cppcheck which interprets this as a single include directory.
This leads to errors like this one (because the "build" dir was missing):

	src/common.h:4:0: information: Include file: "config.h" not found. [missingInclude]
