libgsm: fix incorrect id on some systems

using install_name_tool -change to change the library ID name did not work on newer systems
use install_name_tool -id instead to change it.

Added support for the Makefile library version to reflect the source version
this will be done dynamically now using ${version} and reinplace
will make updating in the future simpler and less error-prone

bump revision to pass these changes through
no dependents as yet so no need to bump any
