perf symbol: Simplify kernel module checking

In dso__load(), it checks if the dso is a kernel module by looking the
symtab type.  Actually dso has 'is_kmod' field to check that easily and
dso__set_module_info() set the symtab type and the is_kmod bit.  So it
should have the same result to check the is_kmod bit.
