sysutils/dtc: Update to 1.4.6 and add test support

dtc 1.4.6 was released 2018/01/03 with various additional checks and
bugfixes, as well as support for some syntactic sugar for overlays that
allows the following:

==
/dts-v1/;
/plugin/;

&foo {
  status = "okay";
};
==

Issues addressed by the previous patches have been fixed upstream, and the
two patches included here have been accepted upstream following the release
of 1.4.6. The patches, along with the TEST_ENV, will be able to go away when
1.4.7 is released.

While here, hook up the test suite and flip maintainer over to uboot@.
