tools/nolibc: use __builtin_offsetof()
The current custom implementation of offsetof() fails UBSAN:
runtime error: member access within null pointer of type 'struct ...'
This means that all its users, including container_of(), free() and
realloc(), fail.
Use __builtin_offsetof() instead which does not have this issue and
has been available since GCC 4 and clang 3.
