shinit: Add package

This package adds support for /etc/shinit and ~/.shinit files, which
contain commands to be run at the start of all interactive shells.
(/etc/profile and ~/.profile are read for login shells only.)

This is useful for those who regularly open non-login, interactive
shells, for example users of GNU Screen or tmux.

(This is based on a patch[1] I submitted for OpenWrt master, but there
does not appear to be much interest in merging the change.)

(This package uses the ENV shell variable, of which the POSIX standard
has a brief description[2]. The dash manpage[3] also describes how the
ENV variable is handled. (dash is the basis for busybox ash.))
