Profiler: Share the mapped kernel between Profile and DisassemblyModel

Browse source 
There is no point in keeping around a separate MappedFile object for
/boot/Kernel.debug for each DisassemblyModel we create and re-parsing
the kernel image multiple times. This will significantly speed up
browsing through profile entries from the kernel in disassembly view.
