Since the proper signer utility has been introduced in the chroot,
there is no need in generating reduced command option set when
building a self signed image.
Also, the same manifest can be used for all images, self signed or
signed using a fob. The manifest needs to be tweaked for the self
signed images to match the test Key ID.
Since the same base manifest is used for all signings, there is no
need to support the "poor man's json parser" any more.

A recent codebase change included the test RMA reset server public key
in the Cr50 image by default.
Prod images must not include the test key, and luckily recent
modifications of the cr50-codesigner utility allow to swap the keys
before signing. This patch adds the command line option for swapping
the keys and a check to ensure that the signed image includes the
prod key and does not include the test key.
Note that cr50-codesigner would fail to sign if the swap was requested
but the test RMA key was not found in the input .efl file. Thus both
conditions are verified: that the original image includes the test key
and that the signed image includes the prod key.
