```
.debug_line: don't rely on header_length field

Empirically, debug info consumers do not respect this field, or otherwise
consider it to be an error when it does not point exactly to the end of the header.
Therefore we rely on the NOP jump at the beginning of the Line Number Program for
padding rather than this field.

llvm-dwarfdump says the line number data is fine; gdb and
binutils-readelf crap out.
