Public bug reported:

[Impact]

Assuming packages A and B, with A depending on B. A has a failing prerm
script.

Expected behavior:
- A fails to be removed, A and B stay unchanged
Actual behavior:
- A fails to be removed
- B is still removed

This might crash their system (e.g. if A is systemd and B is
libsystemd0).

[Test case]
See Impact. An automated version of the test case (test-apt-get-remove-depends) 
is included and run on autopkgtest.

[Regression potential]
We now abort earlier in removal failures, that might be harder to recover from 
or not, nobody really knows.
