slab: print slabinfo header in seq show
Currently we print the slabinfo header in the seq start method, which
makes it unusable for showing leaks, so we have leaks_show, which does
practically the same as s_show except it doesn't show the header.
However, we can print the header in the seq show method - we only need
to check if the current element is the first on the list. This will
allow us to use the same set of seq iterators for both leaks and
slabinfo reporting, which is nice.
