[PATCH 3/4] kconfig: Look in both /bin and /sbin for lsmod in streamline_config.pl

From: Steven Rostedt <srostedt@redhat.com>

Distributions now have lsmod in /bin instead of /sbin. But to handle
both cases, we look for it in /sbin /bin /usr/bin and /usr/sbin.
If lsmod is not found in any of those paths, it defaults to use
just lsmod and hopes that it lies in the path of the user.
