The main work is done by sbuild, which uses schroot, not "sudo chroot".

(We used to use sbuild's sudo session mode, but I changed that to
schroot in 2017.)

I think schroot does support PAM.  However, I don't think it's good
design for launchpad-buildd to rely on PAM, since after all it's not
doing any kind of interactive authentication.  I would rather not pursue
this option any further.  There are other less complicated ways to set
resource limits.
