dbghelp: Base and symbols.

- report the correct image base for a symbol which is seen as being in a builtin PE module, whilst its debug information is gotten from an ELF module - module_get_debug now returns a pair of modules (the requested that has to be presented back to the client and the effective one, which contains the debug info) - reworked SymFromName in order to provide also the revelant module base address
