This patch updates the xmp-cli copy of list.h with the same fix applied here for libxmp: https://github.com/libxmp/libxmp/commit/91de55837f332fa41035555cedf615d06231568d. Despite mostly working and being supported by everything, the hand-rolled "offsetof" used in this file is technically considered undefined behavior due to containing a dereference of NULL. Since offsetof is ANSI C there's no reason not to use it here.
