package/mke2img: remove package

Now that we use mkfs to generate ext2/3/4 filesystem image by calling
mkfs directly from fs/ext2/ext2.mk, we can remove this package.

-NAME
-    ${my_name} - Create an ext2/3/4 filesystem image
-
-SYNOPSIS
-    ${my_name} [OPTION]...
-
-DESCRIPTION
-    Create ext2/3/4 filesystem image from the content of a directory.
-
-    -b BLOCKS
-        Create a filesystem of BLOCKS 1024-byte blocs. The default is to
-        compute the required number of blocks.
-
-    -i INODES
-        Create a filesystem with INODES inodes. The default is to compute
-        the required number of inodes.
-
-    -r RES_BLOCKS
-        Create a filesystem with RES_BLOCKS reserved blocks. The default
-        is to reserve 0 block.
-
-    -d ROOT_DIR
-        Create a filesystem, using the content of ROOT_DIR as the content
-        of the root of the filesystem. Mandatory.
-
-    -o FILE
-        Create the filesystem in FILE. Madatory.
-
-    -G GEN -R REV
-        Create a filesystem of generation GEN (2, 3 or 4), and revision
-        REV (0 or 1). The default is to generate an ext2 revision 1
-        filesystem; revision 0 is invalid for ext3 and ext4.
-
-    -l LABEL
-        Create a filesystem with label LABEL. The default is to not set
-        a label.
-
-    -u UUID
-        Create filesystem with uuid UUID. The default is to set a random
-        UUID.
-
-  Exit status:
-    0   if OK
-    !0  in case of error
