This patch fixes some scripts for generating source files. For
gen_jit_decompositions.py, gen_mobile_upgraders.py and
gen_jit_shape_functions.py, which depend on the compiled PyTorch library, the
option to generate "dummy" source files is added for the initial build, which
is later corrected. codegen_external.py is patched to avoid duplicate
functions and add the static keyword as in the existing generated file.
