bpf: remove size_of_bpf_{map,prog}_def

Browse source 
No longer needed, since there is no longer any possibility of .o vs loader version skew.

* The size_of_bpf_{map,prog}_def allow the bpfloader to load programs where
* these structures have been extended with additional fields (they will of
* course simply be ignored then).

* If missing, bpfloader_{min/max}_ver default to 0/0x10000 ie. [v0.0, v1.0),
* while size_of_bpf_{map/prog}_def default to 32/20 which are the v0.0 sizes.
