Merge #7068

7068: Bump vendored fileutils to 1.2.0 r=hsbt a=deivid-rodriguez

### What was the end-user problem that led to this PR?

The problem was we manually updated some code in the vendored fileutils instead of using a released version.

### What was your diagnosis of the problem?

My diagnosis was that we should use the recently released fileutils 1.2.0.

### What is your fix for the problem, implemented in this PR?

My fix is to vendor it through `bin/rake vendor:fileutils[v1.2.0]`.

### Why did you choose this fix out of the possible options?

I chose this fix because it properly upgrades the vendored code to match what's last released.
