Subject: [PATCH 7/7] perf tools: Enhancement for perf list with --raw-dump.

As we make --raw-dump work as a proper option, we need to
make the output of it more readable.

Example:
	# ./perf list kvmmmu --raw-dump
        kvmmmu:kvm_mmu_pagetable_walk kvmmmu:kvm_mmu_paging_element
         kvmmmu:kvm_mmu_set_accessed_bit kvmmmu:kvm_mmu_set_dirty_b
        it kvmmmu:kvm_mmu_walker_error kvmmmu:kv

Verification:
	# ./perf list kvmmmu --raw-dump
	kvmmmu:kvm_mmu_pagetable_walk
	kvmmmu:kvm_mmu_paging_element
	kvmmmu:kvm_mmu_set_accessed_bit
	kvmmmu:kvm_mmu_set_dirty_bit
	kvmmmu:kvm_mmu_walker_error
	kvmmmu:kvm_mmu_get_page
	kvmmmu:kvm_mmu_sync_page
	kvmmmu:kvm_mmu_unsync_page
	kvmmmu:kvm_mmu_prepare_zap_page
	kvmmmu:mark_mmio_spte
	kvmmmu:handle_mmio_page_fault
	kvmmmu:fast_page_fault
