uapi/linux/stddef.h: Add include guards
commit 55037ed7bdc62151a726f5685f88afa6a82959b1 upstream.
Add include guard wrapper define to uapi/linux/stddef.h to prevent macro
redefinition errors when stddef.h is included more than once. This was not
needed before since the only contents already used a redefinition test.
