An unprivileged "container" environment like this[1] doesn't have root
account (uid 0) which causes tons of "Invalid argument" warnings:
$ bitbake ...
...
WARNING: Could not copy license file [src] to [dest]: [Errno 22] Invalid argument: '[src]'
WARNING: Could not copy license file [src] to [dest]: [Errno 22] Invalid argument: '[src]'
WARNING: Could not copy license file [src] to [dest]: [Errno 22] Invalid argument: '[src]'
...
Fix it by handling EINVAL similar to existing handling of EPERM (which
was added for when not running under pseudo).
[1]: The real environemnt is buildFHSUserEnv from NixOS/nixpkgs, but a
demonstration of the issue can be done like this:
$ touch f
$ unshare --user --mount chown 0:0 f
chown: changing ownership of ‘f’: Invalid argument
