Use git-format-patch to generate patch

pre-upload.py feeds patches of commits to checkpatch.pl for style check.
However it generates patches using git-show instead of git-format-patch.
The problem with git-show is that its output format is configurable
through git-config, and so it might generate a illegitimate formatted
patch.  Besides, git-format-patch should be used to generate patches
anyway.

BUG=none
TEST=Run commands below:
       cd path/to/kernel
       git config --local --add format.pretty oneline
       path/to/pre-upload.py
     You should see no "ERROR: Missing Signed-off-by: line(s)".
