[PATCH v2 0/9] execute patch commands without an implicit shell

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

Continue the shell=True cleanup in oe.patch.

Run runcmd() argument lists directly instead of joining them into an
implicit shell command string.

This series converts the non test runcmd() callers that invoked it with
-sh.

The series also replaces the cat-to-patch pipeline with patch -i,
removes the obsolete PATCHFILE assignment, converts GitApplyTree
commands to argv lists, and keeps manual-resolution commands as argv
lists.

oelib tests cover argv handling and error reporting, GitApplyTree
patch-name preservation, fallback commit metadata, and run=False
command generation without repository side effects.

Changes in v2:
- Accept both valid Git `%aI` representations of UTC, `Z` and `+00:00`,
  in the fallback metadata test
