    devtool/standard.py: Enable perf to be buildable
    
    Perf is a tool build from the kernel source, which is normally available
    in /work-shared/..., but when devtool is used to modify the kernel
    source code, perf is not buildable since it gets an error about being unable
    to add a depends to a non-exisit task do_patch.
    
    This patch removes do_patch from the SRCTREECOVEREDTASKS and creates an empty
    do_patch task to enable the VarFlags code to have someplace to attach depends
    information to.
