Bug#1126565: adios2: Please use whitelist for libblosc2-dev in Builds-Depends

Hello,

adios2 is currently BD-Uninstallable on ppc64 and sparc64 while it built
there in the past [1]. This is because the build dependency on libblosc2-dev
which is excluded for s390x only.

Since using a whitelist makes more sense than a blacklist, I suggest to use
that, i.e.:

      libblosc2-dev [alpha amd64 arm64 loong64 ppc64el riscv64]

Those are all 64-bit architectures which are little-endian where c-blosc2
builds fine [2].

Thanks,
Adrian
