Export D-Bus interfaces to /usr/share/dbus-1/interfaces

Pass -Ddbus-interfaces-dir=no to meson to disable export

Interfaces from:
org.freedesktop.home1
org.freedesktop.hostname1
org.freedesktop.import1
org.freedesktop.locale1
org.freedesktop.LogControl1
org.freedesktop.login1
org.freedesktop.machine1
org.freedesktop.oom1
org.freedesktop.portable1
org.freedesktop.resolve1
