modpost: remove mod->is_dot_o struct member
Previously, there were two cases where mod->is_dot_o is unset:
[1] the executable 'vmlinux' in the second pass of modpost
[2] modules loaded by read_dump()
I think [1] was intended usage to distinguish 'vmlinux.o' and 'vmlinux'.
Now that modpost does not parse the executable 'vmlinux', this case
does not happen.
[2] is obscure, maybe a bug. Module.symver stores module paths without
extension. So, none of modules loaded by read_dump() has the .o suffix,
and new_module() unsets ->is_dot_o. Anyway, it is not a big deal because
handle_symbol() is not called for the case.
To sum up, all the parsed ELF files are .o files.
mod->is_dot_o is unneeded.
