bpf: align function entry point to 64 bits
Libbpf does not treat paddings after functions well. If function
symbols does not cover a whole text section, it will emit error
similar to:
libbpf: sec '.text': failed to find program symbol at offset 56
Each instruction in BPF is a multiple of 8 bytes, so align the
functions to 8 bytes, similar to how clang does it.

* config/bpf/bpf.h (FUNCTION_BOUNDARY): Set to 64.
