Git will refuse to modify untracked nested git repositories
(directories with a .git subdirectory) unless a second -f is given.

This adds the ability to pass "-ff" to git clean to enable removing
directories with a .git subdirectory.

An example use case is when a gem from a git source is cached in
vendor/cache/some_gem
Removing this with "git clean" would require "git clean -dff"
