Subject: [PATCH] fix(tests/functional/repl): skip test if stack size limit is
 insufficient

Nix attempts to set the stack size to 64 MB during initialization, which is
required for the repl tests to run successfully. Skip the tests on systems
where the hard stack limit is less than this value rather than failing.
