From: Derrick Stolee <dstolee@microsoft.com>

The File System Monitor (FS Monitor) tests in t7519 demonstrate some
important interactions with the index and the response from the FS
Monitor hook. Later changes will integrate the FS Monitor extension in
the index with the existence of sparse directory entries in a sparse
index. To do so, we need to include directories outside of the sparse
checkout definition.

Add a new directory, dir1a, between dir1 and dir2 in the test repo used
by this script. By inserting it in the middle, we are more likely to
trigger incorrect behavior when the fsmonitor_dirty bitmap is involved
with sparse directories changing the position of cache entries.

I could have modified the test to create two repos, one sparse and one
not, but that causes confusion in the expected output. Further, it makes
the test take twice as long. With this approach, we can validate that FS
Monitor works with the sparse index feature using the
GIT_TEST_SPARSE_INDEX=1 environment variable. The test currently fails
with that environment variable because FS Monitor is disabled when a
sparse index exists. The following changes will update this behavior.
