devtool upgrade's changelog extraction misattributed unrelated commits
when upgrading recipes like nghttp2, whose ChangeLog is the literal output
of `git log`, regenerated wholesale on every release.

Changes from v1:
- Header-skipping in the structural diff now relies on the blank line
  git log always inserts before the commit message, instead of
  enumerating header prefixes with a regex.
- The UTF-8 decode fix is split into its own patch and applied to both
  git-show call sites instead of just one.
- A single-use helper that only sequenced two operations with no reuse
  benefit has been inlined into its caller.
- The git-diff fallback is now guarded against UnicodeDecodeError too,
  so a bad byte in the diff hunk itself doesn't crash extraction.

Changes from v2:
- drop already merged patch.
- as suggested in the review use subprocess.run() and drop helper function

Daniel Turull (2):
  devtool: upgrade: call subprocess.run() instead of bb.process.run()
  devtool: upgrade: diff git-log-style changelogs by commit hash
