tests: copy 01autoremove from the right place

With cmake using BUILDDIRECTORY at this place is not only as wrong as it
was before, but it might not even work always copying the system
provided one which might or might not be current and hence fails tests
needing it to be current like ./test-apt-move-and-forget-manual-sections

We don't want to always use the one from the source directory through
either like in autopkgtests.
