pylibfdt: Work-around SWIG limitations with flexible arrays
Commit a41509bea3e7 ("libfdt: Replace deprecated 0-length arrays with
proper flexible arrays") fails to build pylibfdt:
./pylibfdt/libfdt_wrap.c: In function ‘_wrap_fdt_node_header_name_set’:
./pylibfdt/libfdt_wrap.c:4350:18: error: cast specifies array type

Turns out this is known issue with SWIG: https://github.com/swig/swig/issues/1699
Implement the work-around to ignore the flexible array member.
