"exclude" paths are ignored when passing absolute paths to csscomb

[cy6erskunk]

• current directory is /home/user/project
• there's following value in /home/user/project/.csscomb.json:

"exclude": [
  "node_modules/**"
]

• css files are passed to csscomb from find /home/user/project -name '*.css' command, which returns absolute paths

As a result all css files from node_modules are checked despite of exlude option

It is minimatch-specific behaviour, it can be "fixed" (with some caveats) by writing "**/node_modules/**", but it would be nice if csscomb could try to cut off pwd from the beginning of the absolute path.
