Makefile: Enable DELETE_ON_ERROR for all targets

If a target is interrupted in the middle of writing an output file, the
file could be left in a corrupt state. A subsequent make invocation will
see the file as up to date and can cause very confusing errors.

BUG=b:112267918
TEST=Made a target fail before completion and verified make deleted the
output file.
