When parsing /proc/xxx/maps, the sscanf in perf_event__synthesize_mmap_events truncate the map name at the space in "/anon_hugepage (deleted)". is_anon_memory then only receive the string "/anon_hugepage" and do not detect it. We change is_anon_memory to only compare the first part of the string effectively ignoring if the (deleted) part is there or not.
