selftest/bpf: Adapt inline asm operand constraint for GCC support
GCC errors when compiling tailcall_bpf2bpf_hierarchy2.c and
tailcall_bpf2bpf_hierarchy3.c with the following error:
progs/tailcall_bpf2bpf_hierarchy2.c: In function 'tailcall_bpf2bpf_hierarchy_2':
progs/tailcall_bpf2bpf_hierarchy2.c:66:9: error: input operand constraint contains '+'
66 | asm volatile (""::"r+"(ret));
| ^~~
Changed implementation to make use of __sink macro that abstracts the
desired behaviour.
The proposed change seems valid for both GCC and CLANG.
