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):
    File ".../scripts/devtool", line 344, in <module>

    File ".../poky/bitbake/lib/bb/process.py", line 178, in run
      raise ExecutionError(cmd, pipe.returncode, stdout, stderr)
  bb.process.ExecutionError: Execution of 'git commit -a -m
  "Committing local file symlinks

  %% ignore"' failed with exit code 1:
  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.
