package/smcroute: prune old smcroute compat script

Long ago, before SMCRoute had yet become a proper daemon and standalone
control tool, it was both.  After the metamorphosis commands and options
had changed, a compat script was added to provide a smooth transition.

The compat script is still shipped in the tarball, and installed, but
only Debian still relies on it, so we prune it here to keep confusion
to a minimum, hopefully.
