build: Fix dtc-checkout race condition in Makefile

build: automatically handle GIT submodule checkout for dtc
On my system, I see the following with a fresh clone:
% ./configure --disable-gtk --target-list=aarch64-softmmu
% make -j8
GEN aarch64-softmmu/config-devices.mak.tmp
GEN config-host.h
mkdir -p dtc/libfdt
GIT ui/keycodemapdb dtc
mkdir -p dtc/tests
GEN qemu-options.def
[snip]
GEN migration/trace.h
make: *** [git-submodule-update] Error 1
make: *** Waiting for unfinished jobs....
Upon closer inspection, the root cause of the error is:
% git submodule update --init ui/keycodemapdb dtc
fatal: destination path 'dtc' already exists and is not an empty directory.
Clone of 'git://git.qemu-project.org/dtc.git' into submodule path 'dtc' failed
This patch fixes this race condition by forcing the 'dtc/%' rule which caused
'dtc' to be non-empty to wait on '.git-submodule-status'.
