[PATCH v2 for-8.0 0/5] scripts/make-release: Decrease size of the release tarballs

[Thomas Huth]

Our release tarballs are huge - qemu-7.2.0-rc2.tar.xz has a size of 116
MiB. If you look at the contents, approx. 80% of the size is used for the
firmware sources that we ship along to provide the sources for the ROM
binaries. This feels very wrong, why do we urge users to download such
huge tarballs while 99.9% of them never will rebuilt the firmware sources?
We were also struggeling a bit in the past already with server load and
costs, so we should really try to decrease the size of our release tarballs
to a saner level.

So let's split the firmware sources into a separate tarball to decrease
the size of the main QEMU sources tarball a lot (which should help us
to safe a lot of traffic on the server).

Additional improvements for the make-release script add a little help text
and speed it up by downloading less data from the various git repositories.

v2:
 - Move the firmware sources into a separate tarball instead of dropping
   the edk2 and skiboot sources.
