cext: fix potential memory leaks of list items appended with PyList_Append

Also reduce the duplication in the tricky code that uses PyList_Append by
extracting it into a function `pylist_append_owned`.

# A utility extension that help taking a break during streamclone operation
#
# This extension is used through two environment variable
#
# HG_TEST_STREAM_WALKED_FILE_1
#
#   path of a file created by the process generating the streaming clone when
#   it is done gathering data and is ready to unlock the repository and move
#   to the streaming of content.
#
# HG_TEST_STREAM_WALKED_FILE_2
#
#   path of a file to be manually created to let the process generating the
#   streaming clone proceed to streaming file content.
