JS: support -Xskip-metadata-version-check for incompatible ABI libraries

Allow the compiler to read such libraries without any errors, at the
risk of crashing with an exception.

Also fix a minor bug in the diagnostic message in LibrarySourcesConfig
and in the corresponding test in KotlinJpsBuildTest
