OpenZFS restructuring - move platform specific sources
Move platform specific Linux source under module/os/linux/ and update the build system accordingly. Additional code restructuring will follow to make the common code fully portable. Reviewed-by: Jorgen Lundman <[email protected]> Reviewed-by: Igor Kozhukhov <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Matthew Macy <[email protected]> Closes #9206
