test: fix subtest nodejs#1, nodejs#2 of test-node-run

Subtest nodejs#1, nodejs#2 of test-node-run.js originally matched the error message
"Can't read package.json" on non-existent file. However, the subtests
failed on Ubuntu20.04. we found that attempting to run a non-existent
script like `node --run foo` using the latest version of node results in
an error message like `Can't find “scripts” field in package.json`
(on Ubuntu20.04, regardless of whether package.json is present in the
subpath or not). So we modified the subtest so that if we match either
of the two messages, the test passes.
