Subject: util/release: Improve git worktree checks

The bash script `genrelnotes` checks for `.git` to be present to
determine whether the current directory is the top directory of a git
worktree. This check is rather weak and doesn't handle many edge cases
like that of a broken gitfile.

Add a proper `git rev-parse` call to check the condition.
