Add the _find0() helper function
The function is a simple wrapper around GNU find(1) which presumes the
intent to use the -files0-from option to read NUL-delimited path names
from the standard input. The benefit in having it is twofold. Firstly,
the _select_by_mtime() and is_older_than() functions are thereby made a
little easier to read. Secondly, the genfun_bin_find variable is now
initialised lazily.
