[LINTER] Integrate lint-locale-dependence.sh into arcanist

Summary:
Change the linter to accept a file as an argument, and always return 0
to avoid arcanist to throw a script execution error.
Add a php class to interpret the linter output and display linting error
messages through arc lint.

Depends on D2704

Test Plan:

arc lint

Comment any of the known exception in the linter-locale-dependence.sh
file and add a comment in the corresponding source file. Check that `arc
lint` displays errors for the source file.
