Auto merge of #27625 - wthrowe:find, r=alexcrichton

New enough find on Linux doesn't support "-perm +..." and suggests
using "-perm /..." instead, but that doesn't work on Windows.
Hopefully all platforms are happy with this expanded version.

I don't have access to a Windows development system to test this, so someone needs to verify that this actually works there before merging.

Closes #19981.
