fix: do not hard fail if Corepack home folder cannot be created

Fixes: #379

Please add a test, one that runs HOME="/tmp/some/folder/here" yarn -v should be enough to reproduce the issue.

The reason the tests didn't catch it is because we specifically disable it:

corepack/tests/main.test.ts

Line 14 in 4a8ce6d

process.env.COREPACK_DEFAULT_TO_LATEST = `0`;

If we re-enable it, it will cause the nock to be outdated as soon as Yarn publish a new version (if we use yarn -v) which is not ideal.
