kbuild: clean compressed initramfs image
Since 9e3596b0c653 ("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".
