AP_ROMFS: don't list a file as though it were a directory

Browse Source 
dir_list() accepted a name matching dirname exactly, so opendir() of a
file's path succeeded, and readdir() then skipped past the end of that
file's name, taking the name from whatever followed it in memory. Over
MAVFTP, listing a path such as @ROMFS/locations.txt was enough.

Match only names with a separator after dirname.
