deps builld: Try to honour CMAKE_BUILD_PARALLEL_LEVEL (#13158)

Browse Source 
* deps: Use CMAKE_BUILD_PARALLEL_LEVEL for dependency builds.

If set when initial CMake is run, don't hard-code the number of CPUs for all the
recursive child builds.

* build_linux: Pass -j1 for dependency build.

This is recommended by the comment at the top of deps/CMakeLists.txt, and makes
sense as the recursive build steps will pick up
CMAKE_BUILD_PARALLEL_LEVEL (otherwise the number of parallel jobs is squared).
