bpf: Disallow interpreter fallback for gotox insn

In the Linux kernel, the following vulnerability has been resolved:

bpf: Disallow interpreter fallback for gotox insn

The interpreter does not recognize the BPF_JMP|BPF_JA|BPF_X insn, which
is used for insn_array map. Thereafter, it would hit the BUG_ON() in
___bpf_prog_run() at run time.

[    2.563726] BPF interpreter: unknown opcode 0d (imm: 0x0)
[    2.564557] ------------[ cut here ]------------
[    2.565206] kernel BUG at kernel/bpf/core.c:2349!
[    2.565882] Oops: invalid opcode: 0000 [#1] SMP PTI

Set jit_required as true when insn_array map is used in the prog in
order to disallow interpreter fallback for gotox insn in
core.c::__bpf_prog_select_runtime().
