    profile: Use _IO* but disable deprecation warning.
    
    This fixes a regression introduced in
    2f60084f77815f454d1521396c2a383390ea2865, whereby the profile derivation
    would fail to run on Guile 2.0 (as is the case with "guix package
    --bootstrap").
    
    Reported by Christopher Baines.
    
    * guix/profiles.scm (profile-derivation)[builder]: Use _IO* but add
    'debug-disable' call.
