selftests/bpf: Fix build of task_pt_regs test for arm64
struct pt_regs is not exported to userspace on all archs. arm64 and s390
export "user_pt_regs" instead, which causes build failure at the moment:
progs/test_task_pt_regs.c:8:16: error: variable has incomplete type 'struct pt_regs'
struct pt_regs current_regs = {};
Instead of using pt_regs from ptrace.h, use the larger kernel struct
from vmlinux.h directly. Since the test runner task_pt_regs.c does not
have access to the kernel struct definition, copy it into a char array.
Fixes: 576d47bb1a92 ("bpf: selftests: Add bpf_task_pt_regs() selftest")
