Subject: [PATCH] Add alternative way to set BROPATH for running bro from
 build/ dir.

Adds two extra shell scripts, one to handle either the c-shell
or bourne-shell syntax for setting environment variables, that can
be sourced in order to set the BROPATH directly in the current
shell/environment in a way that's compatible with running bro
from the build/ directory.
