Rusty Russell 131e79ab91 channeld: don't ever use 0 as a feerate.
This has been reported several times on regtest, most recently by Gijs
van Dam.  It turns out approx_max_feerate() was returning 0 in some
corner cases: we should *not* be using that value (as shown, it's
overly conservative) except as a ceiling on fee *increases*.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: Protocol: don't ever send 0 fee_updates (regtest bug).
