fiptool: Add Amlogic BL301 UUID and command line option

The --blob uuid=AABBCCDD-ABCD-EFEF-ABCD-12345678ABCD,file=... option places
this custom TOC entry last. This is because pack_images() walks through
the list of image descriptions sequentially, and the --blob option
appends to the end of the list in create_cmd(). The command line order
of options is thereby not taken into account.

But firmware blobs expect a load offset resulting from ordering bl301
between bl30 (aka scp-fw) and bl31 (soc-fw).

Therefore add an entry to toc_entries[] for usage by fill_image_descs().
Place the UUID inline to avoid mistaking it for anything official, and
name the commandline option "amlogic-scp-task-fw".

See afaerber/meson-tools#3 for more background.
