sys-apps/sed: use bootstrap logic with USE=forced-sandbox #650052

The build system runs sed scripts that use r (read) commands, so if the
system version had sandbox enabled, we won't be able to rebuild sed.
Use the existing bootstrap logic so people can enable/disable this flag
on the fly w/out wedging their systems.
