Subject: _post_src_install_soname_symlinks: fix bug 543818

The SonameDepsProcessor.add() method raises AssertionError if the
multilib category of an ELF file is not recognized. It's not possible
to account for soname dependencies in this case (the file is probably
intended for a foreign architecture), so avoid the AssertionError and
generate an eqawarn message for this case. The eqawarn message is
suppressed for files matched by the QA_PREBUILT variable.
