t5003: skip unzip -a tests with BusyBox

BusyBox' unzip is working pretty well. But Git's tests want to abuse it
to not only extract files, but to convert their line endings on the fly,
too. BusyBox' unzip does not support that, and it would appear that
it would require rather intrusive changes.

So let's just work around this by skipping the test case that uses
`unzip -a` and the subsequent test cases expecting `unzip -a`'s output.
