Subject: test: Check that apt-ftparchive handles deep paths

This checks for the previous boundaries for path sizes; but
we also added a check for many files in a directory, limited
to 4096.

Sadly the directory check did not fail with the old code either,
it's hard to actually get it to fail correctly.
