perf tools: Add file_only config option to strlist

Browse source 
If strlist_config.dirname is present, the strlist__new() tries to load
stirngs from dirname/list file first but if it failes it falls back to
add 'list' as string.  But sometimes it's not desired so adds new
file_only field to prevent it.
