Don't install a pkg-config file for libdt

libdt isn't supposed to be installed as a system library as nobody wants
to care about things like a stable API. Also the generated .pc file is
completely bogus as it adds "-labc" to the linker instead of -ldt-utils.

So just drop generating and installing the pkg-config file.
