Naveen N. Rao fab07611fb powerpc32/bpf: Fix codegen for bpf-to-bpf calls 
Pad instructions emitted for BPF_CALL so that the number of instructions
generated does not change for different function addresses. This is
especially important for calls to other bpf functions, whose address
will only be known during extra pass.
