Migrate -proc:full setting to a profile

I misread the linked notice about the new -proc:full option, thinking
it would be available with OpenJDK 8u411+, but for Java 8 it's only
available in Oracle's flavor of Java, not OpenJDK. So we instead wrap
the setting in a profile that activates only as appropriate.
