build-unit-test-docker: workaround boost and clang-16 issues

Add a patch to work around the issue discussed in boostorg/beast#2648
and observed in bmcweb testing.  This patch is only necessary in our
Docker container, and not Yocto, because we only compile with clang
or clang-tidy in the Docker environment.
