bitcoin.py: split dust_threshold from minrelayfee, make it hardcoded instead

Browse Source 
- the dust threshold in bitcoin core is calculated with a 3 sat/vbyte feerate,
  which we were interpreting as 3*minrelayfee
- and now bitcoin core is considering changing the minrelayfee (1->0.1 s/b),
  independently from the dust threshold
  (in https://github.com/bitcoin/bitcoin/pull/33106)
