Avoid opening dirs as files

[nfroidure]

Doing this on my blog:

reachable-urls contents/**

⠋ Checking files(node:19427) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: EISDIR: illegal operation on a directory, read
⠸ Checking files
⠧ Checking files^C

Fails since your program try to open dirs as files. You should use an option to not list dirs whith your glob dependency. Something like that: https://github.com/nfroidure/metapak/blob/master/src/assets.js#L54

The above errro led to: #1
