PLUGINS: Simplify ELF plugin providers & DLObject subclasses

* Remove DLObject virtual methods allocSegment and freeSegment.
  As long as all DLObject implementations use memalign + free to
  allocate/release segments, there is no point in wrapping those.
  This enables further simplifications.
* Add TemplatedELFPlugin template class. Use this instead of explicit
  ELFPlugin subclasses.
* Rename DLObject::discard_symtab to discardSymtab
