[strongSwan] Android doesn't support ESP aes256gcm16-modp2048

[Tobias Brunner]

Hi Piotr,

> it seems that Android app doesn't support cipher esp=aes256gcm16-modp2048

Correct.  That proposal is not supported by the app, see [1] for the
list of currently configured proposals.  So you basically have to use a
stronger DH group when using aes256gcm16.
