apertis-abi-compare: don't fail in case of soname change

When the soname changes, the name of the binary package changes
accordingly. In this case, ABI breakage is expected thus there is
no need to run abi-compliance-checker. apertis-abi-compare detects
this case and report the soname change without failing.
