Adds support to create img from target files directory instead of zip. 

This is used by merge_target_files to prevent an unnecessary unzip and
copy.

Test: Ran merge_target_files.py and booted using the img.zip.

Given a target-files zipfile, produces an image zipfile suitable for

use with 'fastboot update'.

Given target-files, produces an image zipfile suitable for use

with 'fastboot update'.



Usage:  img_from_target_files [flags] input_target_files output_image_zip



input_target_files: one of the following:

  - directory containing extracted target files. It will load info from

    OTA/android-info.txt and build the image zipfile using images from IMAGES/.

  - target files package. Same as above, but extracts the archive before

    building the image zipfile.



Flags:

  -z  (--bootable_zip)

      Include only the bootable images (eg 'boot' and 'recovery') in

      the output.
