[PATCH] base.bbclass: allow specifying an lsb distro hook via the metadata

[Christopher Larson <kergoth@gmail.com>]

From: Christopher Larson <chris_larson@mentor.com>

This is useful when you have a rather large set of compatible distros. For
example: Centos 5.4, 5.5, 5.6, etc, RHEL server 5.x, RHEL workstation 5.x.
