We don't need root with -Sp

Browse Source 
FS#8905 is fixed. The front-end passes PM_TRANS_FLAG_NOLOCK to the back-end,
so it doesn't lock the database. That's why we don't need root anymore.

I reworked (and renamed) needs_transaction() accordingly. I also added
missing -Sc check there (for example, -Sci didn't print non-root error, but
pacman wanted to lock the database).
