Fix up the Mac installer’s Info.plist, build with branding info

 #
 # PREFER NOT TO USE THESE. The GYP build uses this kind of thing extensively.
 # However, it is far better to write an action to generate a file at
 # build-time with the information you need. This allows better dependency
 # checking and GN will run faster.
 #
 # These values should only be used if you REALLY need to depend on them at
 # build-time, for example, in the computation of output file names.
