bpftool: Remove redundant "HAVE" prefix from the large INSN limit check

bpftool: Remove redundant "HAVE" prefix from the large INSN limit check

"HAVE" prefix is already applied by default to feature macros and before
this change, the large INSN limit macro had the incorrect name with
double "HAVE".
