Kernel: Use KBufferBuilder to build ProcFS files and backtraces

Browse source 
This is not perfect as it uses a lot of VM, but since the buffers are
supposed to be temporary it's not super terrible.

This could be improved by giving back the unused VM to the kernel's
RangeAllocator after finishing the buffer building.
