Subject: [PATCH] nim: fix power arch predicates

isPowerPC is only true on 32 bit machines;
to check the family we should use isPower here

Otherwise, e.g. `pkgsCross.powernv.buildPackages.nim` fails to eval with
`error: evaluation aborted with the following error message: 'no Nim CPU support known for powerpc64le-unknown-linux-gnu'`
