RFR: JDK-8151800: Jib profile for open linux should produce compact profiles images by default

[Erik Joelsson]

(note the overloaded use of the word profile in this text)

The linux open only Jib profiles are meant to be used for the reference 
implementation builds. These builds should produce the compact profile 
images in addition to the normal images. This patch changes the linux 
open only Jib profiles to add the profiles make target to the default set.
