Fix inotify for https://github.com/FeralInteractive/gamemode/issues/149

	1. Don't look for ATTRIB changes - these spawn extra unneeded events when other watches will catch actual edits
	2. Move name check code out of IN_ISDIR, I mistook IN_ISDIR to mean the event was from a dir watch, but this was incorrect
