image_types_phosphor: Add do_generate_rwfs_ext4()

Create a new do_generate_rwfs_ext4() function that generates an empty
ext4 rwfs image file of arbitrary size 1MB. This file is needed to create
a tarball image for code update to use. The size can later be updated,
this commit is intended as a first step for creating a tarball with ext4
image files.
