slabinfo: fall back from /sys/kernel/slab to /sys/slab

Browse source 
I keep running upstream and mm kernels and the location of the slab
directory is different since upstream still uses /sys/slab.  This patch
makes slabinfo check /sys/slab if /sys/kernel/slab is not there.  Makes
slabinfo work on any kernel.
