util: set correct stack level on deprecation warnings Without this patch, you'll get something like this: <path>/mercurial/util.py:3784: DeprecationWarning: 'util.hgexecutable' is deprecated, use 'utils.procutil.hgexecutable' (but on one line) Differential Revision: https://phab.mercurial-scm.org/D3331
