Log Message:
Update munin packages to 1.3.2, latest development release
with fixes from the stable branch.

Changes since previous version:

This release implements proper TLS support, as well as all the
bugfixes from the 1.2 stable series.

pkgsrc changes:

* Fixed many pkglint warnings.
* Install munin.conf and munin-node.conf as ${INSTALL_DATA} not
  ${INSTALL_SCRIPT}, I couldn't see any reason why those were
  installed as scripts.
* Added VARBASE into BUILD_DEFS, as suggested by pkglint.
