[rfc][icedtea-web] Ignore invalid .jar files specified for plugin

[Adam Domurad]

So, I realize after some thought that this probably shouldn't be in
JarCertVerifier. However this is where the .jar files are uncompressed
and thus the location where the ZipException could be caught and dealt
with. Suggestions ? To be sure the .jar files are valid they must be
unzipped first, via new JarFile(...).
