system: Add "--" after "-c" for sh (BZ #28519)
Prevent sh from interpreting a user string as shell options if it
starts with '-' or '+'. Since the version of /bin/sh used for testing
system() is different from the full-fledged system /bin/sh add support
to it for handling "--" after "-c". Add a testcase to ensure the
expected behavior.
