package/tpm2-tss: fix build without C++

C++ is required only for the fuzzing tests but AC_PROG_CXX is included
by configure.ac even when fuzzing is not enabled (which we don't do on
Buildroot).

The patch applied upstream had issues and was reverted[1]. Use a local
patch to solve the problem temporaryly.
