check-riscv64: Skip specific tests on riscv64 platforms

A couple of tests are not supported on riscv64 as they have dependencies
(zfs and a pyhton docker image) that are not yet available for riscv64.

Signed-off-by: Francis Ginther <email address hidden>

Found a few testcase issues specific to riscv64. One is caused by docker not publishing a python image for riscv64, the other by zfs support issues.

Looking good, +1.
