Revert "paccache: avoid subshell in calling runcmd"

su is terribad. In addition to reverting, this also removes support for
privilege escalation via su. If you want to use paccache as root and
fail to comprehend how much better sudo is than su, then run paccache
directly via su.

Fixes FS#35173.

This reverts commit 597286eb258f841dfc00f65474138fc6192f0092.
