[PATCH v4 10/13] networkxml2conftest: Use dnsmasqCapsNewFromBinary() to construct caps

[Michal Privoznik]

DISCLAIMER: dnsmasq capabilities are empty as of v8.0.0-rc1~145.

In a real environment the dnsmasq capabilities are constructed
using dnsmasqCapsNewFromBinary(). We also have
dnsmasqCapsNewFromBuffer() to bypass checks that real code is
doing and just get capabilities object. The latter is used from
test suite.

However, with a little bit of mocking we can test the real life
code. All that's needed is to simulate dnsmasq's output for
--version.
