devtool: Avoid failure for recipes with S == WORKDIR and no local files
When extracting the sources for a recipe that has S == WORKDIR and no
local files in the SRC_URI (which, e.g., can happen for a recipe with
a URI that has the unpack=false attribute), the extraction fails with
the following backtrace:
Traceback (most recent call last):

bb.process.ExecutionError: Execution of 'git commit -a -m

On branch devtool
nothing to commit, working tree clean
This is because no files were found in the oe-local-files directory
and consequently no symbolic links were added using `git add`, but the
`git commit` command was still executed.
