[PATCH 7/9] oe/patch: pass GitApplyTree commands as argv lists

[Anders Heimer <anders.heimer@est.tech>]

After removing PATCHFILE from the git-am command, the GitApplyTree apply
and commit commands no longer need shell syntax. Build the commands as
argv lists and pass them directly to runcmd().

Remove shell quoting from git -c, --author and --date arguments now that
those values are passed directly to Git instead of through sh -c. Update
the devtool upgrade caller to use shlex.join() when it still embeds
those options in a shell command string.

Keep run=False command generation as argv lists and avoid adding notes or
committing fallback changes when no command was run. Run the dirty-tree
status check from self.dir so it inspects the patch tree consistently.
