[Buildroot] [PATCH 1/2] package/pocketpy: fix build without threads

pocketpy enables thread support by default (PK_ENABLE_THREADS=ON) and
then requires Threads from cmake, which fails on toolchains without
thread support:

  CMake Error at /usr/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
    Could NOT find Threads (missing: Threads_FOUND)

Thread support is optional, so enable it only when the toolchain
provides threads.
