lib/oe/patch: GitApplyTree: save 1 echo in commit-msg hook

* also remove the extra blank lines which is often added to patches
  when refreshed with devtool (GitApplyTree.patch_line_prefix lines
  are ignored when refreshing .patch files, but newly added blank
  lines aren't - the leading blank line wasneeded for patches with
  just the subject line (to prevent the GitApplyTree.patch_line_prefix
  line ending appended to the commit summary), but we can add it
  in prepareCommit instead
