[OE-core] [PATCH] devtool: ensure temp directory is created

[Joshua Lock]

We often see nightly-oe-selftest on the Yocto Project Autobuilder fail in
test_devtool_modify_native with:

     'devtool modify apt-native -x /tmp/devtoolqahlptvsfq/apt-native' returned
     non-zero exit status 1

and the following traceback:

Traceback (most recent call last):
  File "/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/scripts/devtool", line 331, in <module>
    ret = main()
  File "/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/scripts/devtool", line 318, in main
    ret = args.func(args, config, basepath, workspace)
  File "/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/scripts/lib/devtool/standard.py", line 714, in modify
    initial_rev = _extract_source(srctree, args.keep_temp, args.branch, False, config, basepath, workspace, args.fixed_setup, rd, tinfoil)
  File "/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-oe-selftest/build/scripts/lib/devtool/standard.py", line 545, in _extract_source
    with open(os.path.join(tempdir, 'initial_rev'), 'r') as f:

Ensure the tempdir is created before we try and create any files there.
