RFR: JDK-8177822: Move closed jib configuration for arm platforms to open

[Tim Bell]

Erik:

> When the closed arm port was moved into OpenJDK, we forgot to also
> include the jib profiles configuration for the internal arm builds. This
> patch corrects that. The profiles are still exactly the same as they
> were in closed, which means they build the Oracle ports.
