devtool: Fix do_kernel_configme task

The do_kernel_configme task is no longer part of SRCTREECOVEREDTASKS,
its been removed from the kernel-yocto.bbclass since b72dbb2e4, but
there wasnt a matching patch for devtool for those changes.

This patch enables us to invoke the do_kernel_configme task when
using a devtool workspace, it also prepends a check for an existing
.config file in the source directory and moves it if thats the case,
since when using devtool modify a .config is created and
do_kernel_configme complains about it, this is not the case when
using bitbake since the .config file would be on B instead.

Alowing do_kernel_configme to run also fixes the flow where testing a
new config fragment from devtool workspace isnt added properly
(config queue shows it as ///frg.cfg) and as a side effect it never
gets merged into the final config.
