Fix compile errors related to errno.h

Because errno.h is defined in terms of a syscall we can get into trouble
when one syscall/<FOO.h> ends up include another syscall/<BAR.h>.

Moving errno.h from kernel_includes.h to kernel.h breaks the possible
inclusion issue on some ARM platforms (which arm_mpu.h ends up include
soc.h which ends up include kernel_includes.h which would include
errno.h).
