Globbing can be quite useful when selecting the paths to preserve across operating system updates. So far, the backup/restore mechanism did not support wildcards. This change enables globbing as supported by the busybox /bin/sh.
Note that the code is intentionally kept simple; among other things, busybox sh does not support pushd and arrays.
