[PATCH v2 0/4] mkimage usability fixes

[Joel Stanley]

v2: Move -B and -E out from FIT_SIGNATURE check, and other fixes from
Philippe's review.

Original cover letter:

I was learning about signed FIT today and was unable to convince mkimage
to produce a signature node in my control device tree. It turns out that
Debian's packaged mkimage doesn't enable FIT_SIGNATURE, so the options I
was passing were silently ignored.

There's an existing Debian bug for that[1] but in the mean time this
changes mkimage's behaviour to fail loudly when FIT_SIGNATURE is
disabled.

The first two patches fix some issues I found when testing the third
patch under sandbox_defconfig with FIT_SIGNATURE=n.
