Ensure that Lubuntu Next is only supported for nine months.

Per the recommendation of the Ubuntu Technical Board, this ensures that Lubuntu Next is only supported for nine months, while Lubuntu is supported for three years. The purpose of this is because Lubuntu and Lubuntu Next share the same seed source (unlike in previous cases with, for example, the Plasma transition) but need separate support cycles.

Seems straightforward, but would you mind if we called these NON_LTS_SEEDS instead of REGULAR_SEEDS? I think that would be clearer.

[Simon Quigley (tsimonq2)]

No problem. Thanks!
