Closes #53604.

When `log.showSignature = true`, git prepends signature verification
lines to stdout before the `--format` output. The null-separated parsers
in `crates/git/src/repository.rs` weren't expecting that, so SHAs ended
up corrupted — the git graph detail panel showed "0 changed files" for
every commit, and file history was similarly broken.

Setting `-c log.showSignature=false` in `build_command` is the same
trick we already use for `core.fsmonitor`. It only affects
log/show/whatchanged, so other commands aren't touched.

Verified locally with an SSH-signed repo: before this change the detail
panel said "0 changed files"; after, the modified files show up
correctly.

Release Notes:

- git_graph: Fix breakage that occurs when `log.showSignature` is
enabled
