Debugger: Adjustments to Jamfile.

- Remove duplicate instance of libshared.
- Add linker flags to not export symbols from linked in static libraries.
  Resolves an issue on gcc4 where symbols from libedit and libsolv would clash,
  leading to crashes.
- Add package kit-related headers and libraries.
