[PATCH] test: 9p: switch security_model from mapped to none

[PATCH] test: 9p: switch security_model from mapped to none

[Ahmad Fatoum]

QEMU's security_model=mapped doesn't allow reading host symlinks (those
not created through 9P) and instead returns ELOOP.

Switch to security_model=none, which passes through real filesystem
semantics (including symlinks) while silently ignoring ownership and
permission changes that would require root.
