This commit adds an assertion to an existing try...catch
statement. Unfortunately, assert.throws() cannot be used
because the operation succeeds on some platforms, throws
EINVAL on some platforms, and throws ENOPROTOOPT on
others.

The motivation for this commit is that these two test fail on systems
that have different Name Service Switch configuration settings. A
concrete example of this is when using Red Hat Enterprise Linux (RHEL)
7.

If Name Service Switch is available on the operating system then it
might be configured differently (/etc/nsswitch.conf).
If the system is configured with no dns the error code will be
AI_AGAIN, but if there are more services after the dns entry, for
example some linux distributions skip a myhostname service by default
which would still produce the ENOTFOUND error.

This commit suggests checking for either ENOTFOUND or EAI_AGAIN to
accommodate systems like the ones described above. The references below
indicate that others have run, or are running, into this aswell.

The commit updates test-require-resolve.js to call toLowerCase on the
resolved module instead of the path. Currently this test will fail if
the path to where node exists contains uppercase letters. For example:

```

/root/rpmbuild/BUILD/node-v8.8.0/test/parallel
module.js:515
    throw err;

If `stdin` was closed or referred to a file, this didn't work,
because it was accessed via file descriptor.

Instead, use another generic native object.
