When tpm2-pytss builds, it will parse headers files from tpm2-tss. Those files are fed through cpp via pycparser. Because our cross-compilation environment uses prefixed binaries like `aarch64-unknown-linux-gnu-cpp`, those can't be found by pycparser. This adds a patch to the setup.py to provide the name of the binary. Fixes #302878
