This patch does the following things:

* changes the default search path for lcrso files to /usr/libexec/lcrso
* checks the result of getcwd which can fail and return an error - in
that case handle the error appropriately
* changes a comment that was incorrectly stating only the cwd was being
searched for lcrso files
