devtool: make required tasks be run in kernel build

Set SRCTREECOVEREDTASKS appropriately in the workspace .bbappend file
for kernel recipes. This tries to ensure that all needed tasks (esp.
configure and patch) are run when building the kernel - tasks which
would normally be disabled by externalsrc.bbclass.
