RFR: 8338686: App classpath mismatch if a jar from the Class-Path attribute is on the classpath

[Calvin Cheung]

When a CDS archive is created with `-cp jarA:jarB` where the manifest of jarA contains a class-path attribute (e.g. `Class-Path: jarA1`). The following paths will be stored in the archive: jarA jarA1 jarB.

Currently, during runtime, if the user specifies `-cp jarA:jarA1:jarB`, it will result in class path mismatch and the archive will not be used. This patch addresses this issue to allow the user specifies jar files in the class-path attribute during runtime.

Testing: tiers 1 - 5.
