description:
If /rescue is at the head of $PATH (which is how it starts out in /rescue/sh
unless changed by something - and has been since NetBSD 3) don't blindly
simply change it to a PATH that doesn't have /rescue in it at all.

This doesn't solve the "/rescue/tar execs /usr/bin/gzip" problem completely,
as if PATH is in the environment when /rescue/sh is started, that one will
override the shell's built in PATH, but this is better than nothing.
