ARM: net: bpf: fix stack alignment

commit d1220efd23484c72c82d5471f05daeb35b5d1916 upstream.

As per 2dede2d8e925 ("ARM EABI: stack pointer must be 64-bit aligned
after a CPU exception") the stack should be aligned to a 64-bit boundary
on EABI systems.  Ensure that the eBPF JIT appropraitely aligns the
stack.

Fixes: 39c13c204bb1 ("arm: eBPF JIT compiler")
