NEON vector path of the PMD needs aarch64 support. But it was
enabled for aarch32 build as well because aarch32 build had
cpu_family set to aarch64. So build for aarch32 will fail due
to unsupported intrinsics.

Fixed aarch32 build by updating meson file to execule NEON vector
implementation for aarch32.

With this change, there should be no need for
