perf kmem: Support legacy tracepoints
Commit 11e9734bcb6a7361 ("mm/slab_common: unify NUMA and UMA version of
tracepoints") removed tracepoints 'kmalloc_node' and
'kmem_cache_alloc_node', we need to consider the tool should be backward
compatible.
If it detect the tracepoint "kmem:kmalloc_node", this patch enables the
legacy tracepoints, otherwise, it will ignore them.
Fixes: 11e9734bcb6a7361 ("mm/slab_common: unify NUMA and UMA version of tracepoints")
