bintree: fix TypeError

Fix the syntax around the writemsg() to avoid a TypeError:

  File "/usr/lib/python3.13/site-packages/portage/dbapi/bintree.py", line 1615, in _populate_remote
    writemsg(
    ~~~~~~~~^
        _(
        ^^
    ...<4 lines>...
        noiselevel=-1,
        ^^^^^^^^^^^^^^
    )
    ^
TypeError: writemsg() got multiple values for argument 'noiselevel'
