submodules: Update concat to v4.2.1

This update addresses the bug
https://tickets.puppetlabs.com/browse/MODULES-6545 resulting in a
spurious concat warning from the postgresql module. This commit makes
the minimum update to address this issue, although much newer versions
of the concat module are available at this time (v6.0.0).
