Toshio Kuratomi fcd6d7010d Fixup perms dont rely on privileged user named root (#15482)
* Don't rely on username to check for root privileges

The SSH username isn't a reliable way to check if we've got root privileges on
the remote system (think "toor" on FreeBSD). Because of this check, Ansible
previously tried to use the fallback solutions for granting file access (ACLs,
world-readable files) even on systems where it had root privileges when the
remote username didn't match the literal string "root".

Instead of running checks on the username, just try using `chmod` in any case
and fall back to the previous "non-root" solution when that fails.

* Fail if we are root and changing ownership failed

Since this code is security sensitive we document exactly the expected
permissions of the temporary files once this function has run.  That way
if a flaw is found in one end-result we know more precisely what scenarios
are affected and which are not.
