TestIpcModeOlderClient: skip if client < 1.40
TestIpcModeOlderClient: skip if client < 1.40

This test case requires not just daemon >= 1.40, but also
client API >= 1.40. In case older client is used, we'll
get failure from the very first check:

> ipcmode_linux_test.go:313: assertion failed: shareable (string) != private (string)
