machine: add reference to machine-dbus.h to Makefile.am

Commit 003dffde2c1b93 ("machined: Move image discovery logic into src/shared,
so that we can make use of it from nspawn") moved some definitions from
machine.h to a new machine-dbus.h, but did not include it in Makefile.am

Tested that `make distcheck` works after this fix.
