build: Build GVDB as a Meson subproject

Since recently, GVDB repository includes a minimal meson.build
file to allow building as a subproject without additional
hassles (e.g. shipping supporting files at /subprojects/repofiles/)
Drop our internal copy of GVDB in favor of a subproject built
through Meson.

Since we're updating many years across, there has been GVDB API
updates that we need to adapt to: GvdbTable is no longer a refcounted
object, and gvdb_table_walk() is no longer offered to iterate across
values.

These largely affect our own set of GVDB tests though, the test
for gvdb_table_walk() was dropped, and so is the ref/unref one
(it basically does the same than gvdb/flat_strings, after dropping
the refcounting). These remaining tests stay useful, and should
ideally move into the GVDB repository, so it can run as a separate
suite here.
