When running git-describe(1) with `--dirty`, we will set up a `struct
rev_info` with arguments for git-diff-index(1). The way we assemble the
arguments it causes two memory leaks though:
- We never release the `struct strvec`.
- `setup_revisions()` may end up removing some entries from the
`strvec`, which we wouldn't free even if we released the struct.
While we could plug those leaks, this is ultimately unnecessary as the
arguments we pass are part of a static array anyway. So instead,
refactor the code to drop the `struct strvec` and just pass this static
array directly.
