Greg Thelen b3008938df kbuild: clean compressed initramfs image
[ Upstream commit 6279eb3dd7 ]

Since 9e3596b0c6 ("kbuild: initramfs cleanup, set target from Kconfig")
"make clean" leaves behind compressed initramfs images.  Example:

  $ make defconfig
  $ sed -i 's|CONFIG_INITRAMFS_SOURCE=""|CONFIG_INITRAMFS_SOURCE="/tmp/ir.cpio"|' .config
  $ make olddefconfig
  $ make -s
  $ make -s clean
  $ git clean -ndxf | grep initramfs
  Would remove usr/initramfs_data.cpio.gz

clean rules do not have CONFIG_* context so they do not know which
compression format was used.  Thus they don't know which files to delete.

Tell clean to delete all possible compression formats.

Once patched usr/initramfs_data.cpio.gz and friends are deleted by
"make clean".
