add inkscape wrapper script for Mac OS

The wrapper script is placed in the binary directory of the LyX bundle.
It tries to find the real inkscape command line converter in the
Inkscape.app bundle and starts it or reports an error.
The configure.py is changed for Mac OS to check the presence of
the real inkscape binary in the Inkscape.app bundle.
