Skip bsatn decode proptest (#5361)

# Description of Changes

Attempted to fix this test in #5343, but we're still getting SIGKILLS,
so ignoring for now. This will require more investigation to fix. I've
included what I believe is the reason in the help text and created
[this](#5362) tracker to unskip.
