test-icu-data-dir and test-fs-readdir-ucs2 failing on master

[joaocgreis]

• Version: master
• Platform: Windows and ARM
• Subsystem: test

The last node-daily-master job https://ci.nodejs.org/job/node-test-commit/10810/ failed because of two tests. These failures appear to happen on every run of the surrounding runs of the relevant jobs, suggesting the failures are real.

• parallel/test-icu-data-dir fails on Windows
• parallel/test-fs-readdir-ucs2 fails on Raspberry Pis (arm-fanned)

9330835 appears to cause the problem in test-icu-data-dir. If I revert the change to test-icu-data-dir.js, the test passes. Should be \r\n on Windows.

The parallel/test-fs-readdir-ucs2 failure is explained in nodejs/build#774 (comment) . PR to mark as flaky: #13989

This can be closed now, issues are no longer blocking CI.

• parallel/test-icu-data-dir was fixed in test: fix failure in test-icu-data-dir.js #13987
• parallel/test-fs-readdir-ucs2 was marked flaky but we still need to find a better solution. Discussion can follow in now: node-test-binary-arm doesn't finish build#774
