The codespell dictionary was moved from
`/usr/share/codespell/dictionary.txt` to data/dictionary.txt
under the codespell_lib installation directory.

Checkpatch still uses a default absolute path for it which will
no longer work on new codespell installations unless the path
is specified through --codespellfile.

Detect the codespell dictionary path dynamically during
runtime if the default path or the user provided dictionary
path does not exist.
