gammu: Remove python dependency, fix lib symlinks

This removes the python dependency from the package; according to the
maintainer[1][2] the software does not depend on python.

This also fixes the symlinks for libGammu.so and libgsmsd.so.
Previously, the symlinks were overwritten by $(INSTALL_BIN) with copies
of their sources.
