cmd/covdata: format package comment for 'go doc' rendering

Browse Source 
Due to an errant newline, both 'go doc' and pkg.go.dev currently
interpret the long comment in cmd/covdata/doc.go as a file comment
instead of package documentation.

Removing the errant newline caused 'go doc' to render the comment, but
it does not strip out the interior '//' tokens from the '/* … */'
block.

Removing those tokens and fixing up indentation seems to give
satisfactory rendering.
