Subject: [PATCH] Pass ipcp-accept-remote to pppd

Since https://github.com/ppp-project/ppp/commit/9fe8923419a954fedf8b6d1a6cc07b45f165c1ab,
pppd refuses to accept a different remote IP if we explictly pass one on
the command line. This results in an error like:

pppd: Peer refused to agree to his IP address

Passing ipcp-accept-remote disables this behavior.
