lockdown: avoid crashing when getting system buid fails When userpref_read_system_buid fails to retrieve the buid, systembuid will be set to NULL. It was then unconditionally passed to plist_new_string - which will crash with a NULL argument. See https://bugs.debian.org/730756 for people reporting this happening in the real world. See https://github.com/libimobiledevice/libimobiledevice/commit/1331f6baa1799e41003aa812c0d1bf36193535ea ("lockdown: Make sure to set SystemBUID in generated pair records") for the commit where this problem was introduced.
