[PATCH v3 07/12] serve.c: move version line to advertise_capabilities()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

The advertise_capabilities() is only called from serve() and we always
emit this version line before it, it makes more sense to consider the
capabilities part of a "header" that has the version, so let's move
the writing of the version there.
