    devtool: modify: fix usage on the kernel
    
    When using devtool modify on the kernel, we have to do a bit of a dance
    with tinfoil instances because we only find out that we're working on a
    kernel recipe after tinfoil is initialised, but then we need to build
    kern-tools-native which we're doing just by running bitbake directly.
    With the tinfoil2 changes, a datastore for the recipe that we were
    keeping around across the opening and closing of tinfoil is no longer
    able to be used. Re-parse the recipe to avoid this problem.
    
    (In future this whole thing will be able to be done in the same tinfoil
    instance thanks to tinfoil2, but that refactoring is yet to be done.)
