Review Request: JDK-8210502: jdeps does not handle properly on analyzing a mixture of MR JARs and non-MR JARs

[mandy chung]

To analyze class dependencies of a multi-release JAR file,
jdeps --multi-release option must be specified so that only
entries of the specified version will be analyzed.

This is to fix a bug in jdeps that fails when it is given
both MR JARs and non-MR JARs.  --multi-release option should
be accepted for non-MR JAR files and all unversioned entries
will be analyzed.  The fix is trivial; just remove the check.
