tests: add a short `sleep` in test-status.t

With dirstate-v2 and rhg both enabled, this test would sometimes fail for me
with:

```
--- tests/test-status.t
+++ tests/test-status.t#dirstate-v2.err
@@ -943,7 +943,7 @@
   $ rm subdir/unknown
   $ hg status
   $ hg debugdirstate --all --no-dates | grep '^ '
-      0         -1 set                 subdir
+      0         -1 unset               subdir
```

Meaning that `status` did not write a directory mtime in the dirstate
as expected. This can happen if the observed mtime of the directory is
the same as "current time" at the start of `status`. This current time
is obtained by creating a temporary file and checking its mtime.

Even with ext4 on my system being able to store nanosecond precision,
identical mtime for successive but separate operations is still possible
becuse the kernel may cache the current time:

0.1 second should be enough for this cache to be updated, without
significantly slowing down the test.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.

Notes for packagers
===================

Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
