Use ignore_cleanup_errors on the DstRect-cap test tempdirs

The new test cases on this PR write a source TIFF inside a
TemporaryDirectory before invoking read_vrt. On Windows the read
path can leave a file handle open just past the context exit, so
shutil.rmtree raises WinError 32 (same shape as #1748). Linux closes
in time and never trips.

ignore_cleanup_errors=True keeps the cleanup best-effort. The
assertions still run inside the context so a real failure still
fails the test; only the tempdir teardown is now tolerant.
