This patch fixes ticket #1083 in the ghci debugger

A module loaded under debugging mode but owning no breakpoints was erroneously identified by ghci as a non-under debugging module, producing a confusing error msg when the user tried to set a breakpoint

The fix inserts an empty list of sites in the module-sites dictionary used by the debugger
