chmodSync throws EISDIR for directories

[dabbott]

Running chmodSync on a directory fails with EISDIR:

var { fs } = require("memfs")

fs.mkdirSync('/foo')
fs.chmodSync('/foo', 0o666)

The error is: Error: EISDIR: illegal operation on a directory, open '/foo'.

(Try it: https://runkit.com/dabbott/memfs-chmodsync/1.0.0)

The same calls seem to work with node's built-in fs, as long as it's a directory where you have permission to write, so I'm guessing this is an issue with chmodSync?

If this is a bug I can try to submit a PR. I haven't looked through the code yet, but seems like it'd be a quick change.

Running chmod (not sync) works. Also, running openSync and then fchmodSync works, as a workaround:

var { fs } = require("memfs")

fs.mkdirSync('/foo')
fs.fchmodSync(fs.openSync('/foo', 'r'), 0o666)

Looks like the same issue as #391.
