[PATCH BlueZ 1/5] build-sys: Don't build gdbus several times

[Lucas De Marchi <lucas.demarchi@profusion.mobi>]

We are currently compiling gdbus 3 times: one for tests, one for
bluetoothd and another for obexd.

$ ls gdbus/*watch.o
gdbus/bluetoothd-watch.o  gdbus/obexd-watch.o  gdbus/watch.o

Instead of prepending $(gdbus_sources) to several _SOURCES variable, use
a convenience library.
