app-emulation/qemu: Update live ebuild

Because we want to download all dependencies in fetch phase
(fixed in [1]), we keep a list of subprojects among with their
latest commit hash. Well, in commit [2] qemu bumped
'berkeley-testfloat-3'. Reflect that in our live ebuild.
Unfortunately, I've missed this in qemu-8.2.0 timeframe (in which
the qemu commit was merged), but there's no real harm as these
subprojects are part of dist tar. IOW, it's only live ebuild that
needs to fetch subprojects explicitly.

Also, some patches don't apply cleanly anymore. Rebase them.

Oh, and 'nios2' target was removed [3].

+Subject: [PATCH] also build virtfs-proxy-helper
+
+The Gentoo ebuild splits the qemu build into a softmmu, user and tool
+phase in order to be able to build and link some of the qemu emulators
+statically. This unfortunately has the consequence that we never
+configure with "have_virtfs" and "have_tools" at the same time.
+
+As a workaround, simply build the virtfs userland unconditionally. After
+all, it is a tiny executable.
