Revert "Support handling crashes in lxc containers"

This reverts commit 4ab9fbe1a6b7889a0cd59b1406e8789d52171fd2.

Michal Toman <mtoman@redhat.com> (2014-07-16):

While this adds support for containers that have ABRT installed inside
(unfortunately I am not aware of any at this moment), it completely
breaks the behavior for standard chroots that people are actually using
(especially koji + mock).
