bplist: Fix data range check for string/data/dict/array nodes
Passing a size of 0xFFFFFFFFFFFFFFFF to parse_string_node() might result in a memcpy with a size of -1, leading to undefined behavior. This commit makes sure that the actual node data (which depends on the size) is in the range start_of_object..start_of_object+size. Credit to OSS-Fuzz
