[Buildroot] [PATCH v2 1/3] package/tvheadend: Fix inclusion of dtv-scan-tables files

Bernd, All,

> v2: do not patch header files but use a better moment for copying the dvb files (Yann)

So, even though I find this much better than the previous iteration, it
is broken:

    $ make clean
    $ make tvheadend-patch
    [--SNIP--]
    cp: cannot stat ?/home/ymorin/dev/buildroot/O/target/usr/share/dvb/*?:
    No such file or directory

This is because dependencies are not guaranteed until just before the
configure step.

I have a pending series that adds patch-dependencies, but it's not yet
been applied (search about fixing linux extensions).

In the meantime, I think we should make that hook a pre-configure hook,
rather than a post-extract hook.

Of course, it would work with a standard build, because dtv-scan-tables
sorts before tvheadend. Still, we'd better get it right from the
beginning.

Regards,
Yann E. MORIN.
