IMFS: don't strlen() an unterminated string in IMFS_dir_read().

a43a3466 (IMFS: Implement variable length node names) introduced a
changed to IMFS_jnode_t from being a null terminated string to a
separate unterminated string and length.  IMFS_dir_read() was still
performing a strlen() on this unterminated string though and when doing
an 'ls' in the fileio example I saw that some filenames had garbage
suffixes.
