[Toybox] find crash

[enh]

mentioned on https://android-review.googlesource.com/#/c/170020/:

touch file1
touch file2
touch file2
./toybox find . -mindepth 1 -newer file1 -exec ls {} ;

Program terminated with signal SIGSEGV, Segmentation fault.
#0  do_find (new=0x133a190) at toys/posix/find.c:179
179            if (dl->prev == (void *)1 || !new->parent)


the "-mindepth 1" appears to be a necessary condition.


(really they wanted to use '+' but found that wasn't working, and hit
this crash when investigating.)

(but really they wanted -delete, and to not have to deal with -exec at all.)
