[libvirt PATCH v2] meson: add -Wall and -Wextra explicitly



If someone runs `meson setup --buildtype plain` meson ignores
warning_level=2 that is in our meson.build file. The implication is
that Meson will not automatically add -Wall which enables -Wformat.

This breaks building libvirt from git with the buildtype set to plain.

There is an issue reported [1] to not ignore warning_level silently
and the change to ignore it was done by upstream commit [2].

This change makes Meson print warnings about using warning_level which
as described above doesn't work for all build types.

Chages in v2:
    - add -Wall and -Wextra explicitly regardless of the buildtype
