build: use split stringlist functions from common/utils

The OCaml and Python bindings directly use the utils.c source in
common/utils, mostly for guestfs_int_free_string_list.  That source
contained also functions using gnulib functions, however without
linking to gnulib.  When building with default build flags (e.g. without
as-needed mode), the gnulib symbols cannot be resolved, leading to
unusable OCaml and Python libraries.

As solution, update the common submodule to get the split of the split
of the stringlist functions in common/utils, and adapt the OCaml and
Python bindings:
- both now use stringlists-utils.c instead of utils.c
- fix the Python distutils setup to include only the sources really
  needed
