Pin host-ipmi-hw-example to a specific Git SRCREV

AUTOREV assumes you can reach the remote repository to lookup the most
recent commit.  When setting up a hermetic build, that will fail even
though a local mirror tarball exists.  Pinning the recipe to a specific
revision skips the lookup and just checks out the specified commit from
the local mirror tarball.
