selftest/devtool: Add test to verify "modify virtual/kernel"
The purpose of this test case is to verify that devtool modify works correctly when building the kernel. [YOCTO #10817] Signed-off-by: Jose Perez Carranza <jose.perez.carranza@linux.intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

+ Summary: The purpose of this test case is to verify that
+ devtool modify works correctly when building
+ the kernel.
+ Dependencies: NA
+ Steps: 1. Build kernel with bitbake.
+ 2. Save the config file generated.
+ 3. Clean the environment.
+ 4. Use `devtool modify virtual/kernel` to validate following:
+ 4.1 The source is checked out correctly.
+ 4.2 The resulting configuration is the same as
+ what was get on step 2.
+ 4.3 The Kernel can be build correctly.
+ 4.4 Changes made on the source are reflected on the
+ subsequent builds.
+ 4.5 Changes on the configuration are reflected on the
+ subsequent builds
+ Expected: devtool modify is able to checkout the source of the kernel
+ and modification to the source and configurations are reflected
+ when building the kernel.
