[Libosinfo] [libosinfo PATCH 1/2] syms: "export" private syms

[Fabiano Fidêncio]

In a similar way as done in libvirt (and pointed out by Martin
Kletzander), let's have our private symbols also exported so they can be
used in our tests.

This approach is pretty much identical to the libvirt one and now we've
libosinfo_public.syms and libosinfo_private.syms, which will be used to
generate the libosinfo.syms.
