copy and copySync: reallow copying to subdirectories

In fs-extra 5.0.0, you fixed an issue that said that directories could be copied to their own subdirectories. This is wonderful, but I couldn’t help but notice that it would break some scripts. In some cases, one may want to copy a directory to its subdirectory, and use a filter function to prevent recursion. Perhaps you could give an option which is false by default that allows to copy to a subdirectory?

With v5 this fails and I don’t quite follow the logic.

await fs.copy('db', 'build/db');

yields this error: Error: Cannot copy '/db/util' to a subdirectory of itself, '/build/db/util'

I’m copying db to build/db, not to a subdirectory of db (itself).

I saw this again in v8.0. Trying to copy a symlink over another symlink.
