[PATCH 6/7] libxenstat: honour XEN_RUN_DIR

[Wei Liu <wei.liu2@citrix.com>]

This is because libxl uses XEN_RUN_DIR to generate the socket path for
libxenstat while libxenstat itself uses hard-coded path, which is not
necessary in sync with libxl.

Generate a _paths.h because it is required to make this change work.
