Subject: [PATCH] run-success.mk: Record last successful run

Add a run-success.mk which provides a $(RUN_SUCCESS_CREATE_MARKER)
variable, and include it from run.mk and py-run.mk. If it's not overridden,
it logs the current commit to a marker file if the run succeeds. The marker
file is ignored from Git and cleaned in the context of the distclean
target.

The machinery can be customized by variables:

  RUN_SUCCESS_MARKER is the name of the marker file
  RUN_SUCCESS_RECORD_CMD is the generator for its content

For example, putting this into local.mk or jw-pkg/make/local.mk will record
the hashes of every repository in the entire workspace:

  define RUN_SUCCESS_RECORD_CMD
  make git-log-1
  make git-log-tree-1
  endef
