comms/kermit: the port had been updated and cleaned up (+)
- Update C-Kermit to version 9.0.305 Alpha.04 which integrates both
modern and legacy OpenSSL support (thus drop our local patch)
- Do not install essentially empty dot-files as examples; they also
contain references to full *.ini files which are no longer shipped
as part of the C-Kermit distribution
- The only useful documentation now is README.TXT, install it in the
dedicated option helper target
