README: fix context for CONFIG_DEVPTS_MULTIPLE_INSTANCES
`newinstance` (and `ptmxmode`) options of devpts are _not_ used by
PrivateDevices=. (/dev/pts is shared, similar to how /dev/shm and
/dev/mqueue are handled). It is used by nspawn containers though.
Also CONFIG_DEVPTS_MULTIPLE_INSTANCES was removed in 4.7-rc2
https://github.com/torvalds/linux/commit/eedf265aa003b4781de24cfed40a655a664457e6
and no longer needs to be set, so make that clearer to avoid confusion.
