Fix imgdiag build rules.
Adjust build rules to avoid building a 64-bit imgdiag
executable on host when HOST_PREFER_32_BIT is true.
This CL addresses an imgdiag related build issue that
appeared on the ART Buildbot after system/core was unpinned
from the master-art manifest
by some of our Buildbot configurations:
ninja: error: 'out/host/linux-x86/obj/SHARED_LIBRARIES/libbacktrace_intermediates/export_includes', needed by 'out/host/linux-x86/obj/EXECUTABLES/imgdiag_intermediates/import_includes', missing and no known rule to make it
