RFR: JDK-8206323: Missing some legal notices in docs bundle

[Erik Joelsson]

Hello,

The docs bundle is missing some of the legal notices from the 
jdk.javadoc module. It should just include all the legal files from that 
module. This patch removes the explicit list and uses wildcard to get 
all the files instead.
