util/lint: Unify checks for git worktree

Linters try to determine whether they are running in a git worktree so
that `git grep` can be used instead of `grep`. These checks are done in
different not truly correct ways and thus the linters don't use `git
grep` when running from a worktree subdirectory, e.g. in a git subtree
environment.

Unify checks using `git rev-parse --is-inside-work-tree`.
