[PATCH] udpated-rc.d: Track postinst/prerm/postrm in task checksum

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When these functions change, the package should rebuild but currently it
does not. We need to add the dependencies manually as the dependency
code can't track dynamically created variables.
