busybox: add /usr/bin/stat applet

The busybox defconfig lacks a stat tool, the functionality of which
cannot be reproduced in a way accessible to a shell script running in
a minimal configuration.  Enable, and modify the installation path to
/usr/bin/stat to match the coreutils tool for proper alternatives
handling.

+The coreutils stat binary lives in /usr/bin, fix busybox to use the same path so
