Christian Lamparter 7c2106696d apm821xx: explicitly build the rootfs.img.gz target 
The commit 87b668765e
("image: when using the new image build code, gzip ext4 images by default")

forced that all targets that select the ext4 as the root filesystem
to always compress the generated rootfs. This is fine, but this method
doesn't not allow to append the metadata on a per-target base.

Therefore this patch changes the rootfs image production rule to generate
the gzip step manually. This way the metadata can be appended at a later
date.

# Netgear used an old uboot that doesn't have FIT support.
# So we are stuck with either a full ext2/4 fs in a initrd.
# ... or we try to make the "multi" image approach to work
# for us.
#
# Sadly, the "multi" image has to consists of three
# "fixed" parts in the following "fixed" order:
# 1. The kernel which is in $@
# 2. The (fake) initrd which is in $@.fakerd
# 3. The device tree binary which is in $@.dtb
#
# Now, given that we use the function for the kernel which
# already has a initramfs image inside, we still have to
# add a "fake" initrd (which a mkimage header) in the second
# part of the legacy multi image. Since we need to put the
# device tree stuff into part 3.
