K32W: Fix header paths breaking --check builds (#7620)

Some header paths are specified incorrectly. This is only an error
when generating the build with the --check option:

ERROR at //third_party/k32w_sdk/k32w_sdk.gni:218:3: Source file not found.
  source_set(sdk_target_name) {
  ^----------------------------
The target:
  //examples/lock-app/k32w:sdk
has a source file:
  //examples/platform/k32w/OpenThreadConfig.h
which was not found.

Fix the paths and enable --check.

Tested by:

(cd ./examples/lock-app/k32w; gn gen --check out/debug --args='k32w_sdk_root="/home/spang/sdk/k32w_sdk"'; ninja -C out/debug)
