RFR: JDK-8147934: Remove --with-sdk-name from macosx jib profile

[Erik Joelsson]

The --with-sdk-name in the macosx profile is not needed, and will be 
ignored. Configure complains:

WARNING: Both SYSROOT and --with-sdk-name are set, only SYSROOT will be used

The devkit already enforces the correct sdk name through setting sysroot.
