packages: convert licman and vu-meter to clones, drop .gitmodules

The last two submodules, and the only ones that really built from the
checked-out tree. vu-meter's build.sh now clones into src/ before building
instead of assuming someone ran `git submodule update --init`; licman had no
wrapper at all and gets the usual build.sh/clean.sh pair driving the build
script inside the repository.

With that every package takes its sources the same way and .gitmodules is
gone, so `git submodule update --init` is no longer a step anyone has to know
about. That also settles licman and speakereq being private repositories:
they no longer make a public clone of hifiberry-os fail, they just need
credentials when their package is actually built.

What this gives up is pinning: a hifiberry-os commit no longer names an exact
upstream commit. It never did in practice - the pointers were unused and had
drifted - and pinning can come back as an explicit ref in build.sh, where it
shows up in a diff.

check-packages.py now passes.
