kbuild: tar-pkg: enable communication with jobserver
The buildtar script might want to invoke a make, so tell the parent
make to pass the jobserver token pipe to the subcommand by prefixing
the command with a +.
This addresses the issue seen here:
/bin/sh ../scripts/package/buildtar tar-pkg
make[3]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.
See https://www.gnu.org/software/make/manual/html_node/Job-Slots.html
for more information.
