Subject: [PATCH 1/8] perf tools: Fix bug in 'perf list event_glob'.

As what the usage showing, we can input a event_glob as an argument to list
all symbols. But it does not work well right now.

Example:
	# perf list kvmmmu

	List of pre-defined events (to be used in -e):

This patch make it work well as follows.

Verification:
	# perf list kvmmmu

	List of pre-defined events (to be used in -e):
	  kvmmmu:kvm_mmu_pagetable_walk                      [Tracepoint event]
	  kvmmmu:kvm_mmu_paging_element                      [Tracepoint event]
	  kvmmmu:kvm_mmu_set_accessed_bit                    [Tracepoint event]
	  kvmmmu:kvm_mmu_set_dirty_bit                       [Tracepoint event]
	  kvmmmu:kvm_mmu_walker_error                        [Tracepoint event]
	  kvmmmu:kvm_mmu_get_page                            [Tracepoint event]
	  kvmmmu:kvm_mmu_sync_page                           [Tracepoint event]
	  kvmmmu:kvm_mmu_unsync_page                         [Tracepoint event]
	  kvmmmu:kvm_mmu_prepare_zap_page                    [Tracepoint event]
	  kvmmmu:mark_mmio_spte                              [Tracepoint event]
	  kvmmmu:handle_mmio_page_fault                      [Tracepoint event]
	  kvmmmu:fast_page_fault                             [Tracepoint event]
