Florian Weimer 89e435f355 posix_spawn_file_actions_addopen needs to copy the path argument (BZ 17048)
POSIX requires that we make a copy, so we allocate a new string
and free it in posix_spawn_file_actions_destroy.

Reported by David Reid, Alex Gaynor, and Glyph Lefkowitz.  This bug
may have security implications.
