refactor: remove redundant fOnlySafe argument

The fOnlySafe argument to AvailableCoins is now redundant, since bitcoin#21359 added a similar field inside the CCoinControl struct. Not all code paths set a CCoinControl instance, but when it's missing we can default to using only safe inputs which is backwards-compatible.
