Subject: [PATCH] Add new build rule for running dtc on Android

dtc_static links libfdt statically for simpler test setup.
Otherwise libfdt.so should be manually pushed.
(tested with data, data_bins, and required with rust_test target)

Change-Id: Ic975258c7e0030cbeeb5c8c0df611d8aa439b3c8
Test: Manually
