fuzz: set m_fallback_fee and m_fee_mode in wallet_fees target

[brunoerg]

m_fallback_fee and m_fee_mode are used in GetMinimumFeeRate but we're not setting any value for them in wallet_fees target. That's the reason fuzzing is never reaching the following code:

This PR fixes it.

==> Caveats
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python@3.11/libexec/bin

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.11/site-packages

tkinter is no longer included with this formula, but it is available separately:
  brew install python-tk@3.11

gdbm (`dbm.gnu`) is no longer included in this formula, but it is available separately:
  brew install python-gdbm@3.11
`dbm.ndbm` changed database backends in Homebrew Python 3.11.
If you need to read a database from a previous Homebrew Python created via `dbm.ndbm`,
you'll need to read your database using the older version of Homebrew Python and convert to another format.
`dbm` still defaults to `dbm.gnu` when it is installed.
