perf tools: Correctly identify anon_hugepage when generating map (v2)

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 receives the string "/anon_hugepage" and does
not detect it.  We change is_anon_memory() to only compare the first
part of the string, effectively ignoring if " (deleted)" is there.
