kbuild: allow docproc invocation from external 

- getcwd returns path without a slash at the end, add the slash
- add KBUILD_SRC env support, so that we can specify path for
  kernel (to know where scripts/kernel-doc resides) and SRCTREE
  (for searching files referenced in .tmpl) separately

[v2]
- use KBUILD_SRC instead of a newly introduced environment variable
