This is part of a series of fixes for the linked bug (failure to preserve libraries in some situations).
When unpacking a binpkg to be installed, we should check for the existence of PROVIDES if we're installing any dynamic libraries. If PROVIDES does not exist in that case, this suggests that e.g. scanelf malfunctioned or some corruption occurred.
