apibuild: Don't include the Copyright in the <description> of a module

When building the top level description from a header file the
'parseTopComment' method of the 'CParser' would include all trailing
lines into the <description> field. This was designed to concatenate
multi-line descriptions, but unfortunately in all cases also included
the Copyright statement which followed.

Explicitly end the scanning of the header on a line which starts with
'Copyright (C)' and truncate the spaces from the end of the last item.
