bpf: Embed kernel CONFIG check into the if statement in bpf_getsockopt

This patch moves the "#ifdef CONFIG_XXX" check into the "if/else"
statement itself.  The change is done for the bpf_getsockopt()
function only.  It will make the latter patches easier to follow
without the surrounding ifdef macro.
