dtc: Don't build tests as part of "all"

Currently "make all" for dtc will build (but not run) the testcase
binaries.  This is a problem for cross compiles, because building the
tests will attempt to run the dumptrees utility on the host system,
which won't work if it's cross-compiled of course.

Although it would be possible to separately build host binaries,
there's not a lot of value in doing so since we don't have a facility
for cross-executing the testsuite anyway.

Therefore, remove the tests from the "all" target.  It will still, of
course, be build as a prerequisite to "make check" which will run the
testsuite.
