rust: Preallocate the returned `Vec` in `utils::files::relativize_path`
Profiling `rhg files > /dev/null` on an old snapshot of mozilla-central
(with `perf` and the Firefox Profiler:
https://github.com/firefox-devtools/profiler/blob/main/docs-user/guide-perf-profiling.md)
showed non-trivial time spend in this function and in `realloc`.
This change makes the wall-clock time for that process on my machine
go from ~190 ms to ~150 ms.
