makechrootpkg: Prevent collecting coredumps

Coredumps from build chroots are not generally useful. Prevent
them from being generated.

Avoids a lot of annoyance from the GCC testsuite spawning lots of
systemd-coredump processes.

Just set the soft limit so the user can still raise it in the PKGBUILD
if they insist.
