Fixed the build and install process for the MacOS stlinkv1 driver - added package build

Hi,

the stlinkv1_macos driver was included in a tar file. I fixed the build process and added packagemaker build to produce a package for installation. The driver source itself is not changed. I expanded everything from the tarfile to put it under version control. 

Now you can run make in the directory and the result will be an install package that you can start from the finder. The package contains the 10.6 and 10.7 drivers with a target os check. For convenience I added the package in the repository. 

The build is makefile controlled although only the xcode and packagemaker builds are started. I tested the installation in 10.6.8. 

Regards
