modpost: Initialize builtin_modname to stop SIGSEGVs
Segmentation fault ./scripts/mod/modpost -o vmlinux.symvers vmlinux.o
stops the kernel build. It comes when write_vmlinux_export_c_file()
tries to buf_printf alias->builtin_modname. malloc'ed memory is not
necessarily zeroed. NULL new->builtin_modname before adding to aliases.
Fixes: 5ab23c7923a1 ("modpost: Create modalias for builtin modules")
