cmake: prefer CMAKE_BUILD_PARALLEL_LEVEL

cmake 3.12 introduced this environment variable. Prefer it to passing
PARALLEL_MAKE and PARALLEL_MAKEINST on the cmake command line, because
it gets passed to second stage cmake invocations while command-line
arguments do not (for example, multi-stage clang builds)
