Make mkfs.ubifs honor the WITHOUT_LZO flag, too.
Fixes this build error:

This is done to allow creating images suitable for IMA directory
appraisal. IMA creates a hash for directories and attaches this
hash to the directory itself as an extended attribute. Among other
things the inode numbers of the files are hashed. So, to create
a valid hash in the UBIFS image the evmctl tool needs to know
the inode numbers which the files in the UBIFS image will have.
evmctl will read the inode numbers from the user.image-inode-number
extended attribute. Since extended attributes are inodes themselves
the inode numbers for the generated image will change when the
extended attributes change, so to generate a correctly hashed
UBIFS image, both evmctl and mkfs.ubifs must be run twice:
1) execute evmctl to iterate over the directory tree. This will
create the security.ima and security.evm extended attributes.
The existence of the attributes makes sure that subsequent
calls to mkfs.ubifs will use the same inode numbers. evmctl
will use the inode numbers from the host filesystem in this
step which makes the resulting image unusable
2) execute mkfs.ubifs -a. This will create the user.image-inode-number
extended attributes on files/directories added to the image.
3) execture evmctl again. This time evmctl will pick the inode
numbers from the user.image-inode-number extended attribute
instead of the ones from the host filesystem
4) execute mkfs.ubifs again. This will create the correct image.
The now existing user.image-inode-number extended attributes
are ignored and not added to the image.

This adds extended attribute support to mkfs.ubifs. When creating
an image from a directory tree the existing extended attributes are
added to the UBIFS image.

A 'non_existing' argument which is only used with !non_existing
is just too confusing. Change this to positive logic.

* There is no code modification in this commit, only moving
* the files to proper place.
The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.
mtd-utils/
|-- lib
|-- include
|-- misc-utils
|-- jffsX-utils
|-- nand-utils
|-- nor-utils
|-- ubi-utils
|-- ubifs-utils
`-- tests
