Patch build files to also system libraries instead of bundled ones for the
libraries not supported or working only by specifying USE_SYSTEM_LIBS.  This
includes using the clog, cpuinfo, fbgemm, foxi, fp16, fxdiv, googletest,
ideep, miniz, nnpack, oneapi-dnnl, pocketfft, pthreadpool, qnnpack,
qnnpack-pytorch, tensorpipe, valgrind and xnnpack packages.
For QNNPACK, two versions were bundled and are required: The upstream one and
an internal fork (now in the package qnnpack-pytorch).
