[PATCH master 4/4] sandbox: actually build the assembly setjmp/longjmp/initjmp

arch/sandbox/Makefile adds the host's um/ directory to pbl-y, but Kbuild
only consumes core-y from the arch Makefile, so the assembly
implementation selected by CONFIG_SANDBOX_SJLJ_ASM was lost.

Use core-y, so the assembly version overrides the weak C one.

Fixes: 48d0d0cc28ed ("kbuild: sync with Linux v6.17")
