unclosed InputStream on Bundle.start

This bug was first observed on Windows 10:  An exploded bundle with an activator is started then uninstalled.  A handle to the bundle's manifest is held by the JVM until shutdown so, in particular, the Manifest can't be modified or deleted.

This is caused by an unclosed InputStream:

When Java major version is greater than 8 and a Bundle with an activator is started,
org.apache.felix.framework.util.MultiReleaseContent.wrap is called. It calls Content.getEntryAsAstream and the resulting InputStream is neither closed nor returned.
