t7519: avoid file to index mtime race for untracked cache
In t7519 there is a test that writes files to disk, and immediately
writes the index with the untracked cache. Because of
mtime-comparison logic that uses a 1-second resolution, this means
the cached entries are not trusted/used under some circumstances
(see read-cache.c#is_racy_stat()).
Untracked cache tests in t7063 use a 1-second delay to avoid this
issue, but we don't want to introduce arbitrary slowdowns, so instead
use test-tool chmtime to backdate the files slightly. The t7063
delays are a #leftoverbit, to be worked on in a separate series.
This change doesn't actually affect the outcome of the test, but does
enhance its validity, and becomes relevant after later changes.
