Subject: tools/mtime.sh: Parse ls output with read, not cut

cut treats multiple delimiter characters as empty fields, increasing the
field count an indeterminate amount for fields with whitespace delimiter
padding.  BusyBox's ls outputs:

    -rw-r--r--    1 1000     1000          1935 Mar 16 16:31 man/opkbuild.1in

cut counts the owner field, not the month, as field 6.  And fields 7 and
8 are empty.

The shell interpreter's field splitting is better suited for this job,
so just use read.
