update-initramfs: Depend on kernel hook scripts rather than $ramdisk invocation

Browse Source 
Official Debian and Ubuntu kernel packages will invoke us directly as
part of the $ramdisk handling inherited from kernel-package.  They
will later run our hook script, as will custom packages made with
'make-kpkg' or the upstream 'make deb-pkg'.

Currently, for official packages we perform an update on the first
invocation (possibly deferred using dpkg triggers) and then ignore the
second.  However, the long-term plan is to remove that first
invocation.  Therefore, ignore the first invocation and perform the
update on the second.
