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.
