RFR 7142950: jdk7u cannot bootstrap Mac OS build [macosx]

This is an updated webrev based on the contribution/suggestion from 
Scott Kovatch.
It changes the build image directories on Mac, to have the same 
format/directory structure
as the other platforms (ie. it removes the Contents/Home stuff). That 
directory structure
required by Mac bundles is now generated in specific bundle directories 
and these
are used by the install. A consequence of this change is that anyone who 
has adjusted
scripts that used the built j2sdk-image, or j2re-image to know about the 
mac specific paths will have to change
that back again.

This version of the change is almost agnostic on the "os.arch" setting. 
The only dependency
is on 'src/macosx/bin/amd64/jvm.cfg'. That will have to be renamed to 
when 'os.arch' is changed. No other change is required.

With this change, jdk only, and incremental builds should work again.
If you are using the previous output from a control build as bootstrap 
or import jdk
for a subsequent jdk only build, then it is possible you could run into 
the build problem
described in 6967648. The workaround is to rename the top-level build 
directory to some
other name before doing the jdk build.
