Update to 1.32:

* Do not force the install target to take a full package name.  pkg_add will
  automatically pick the latest version.

* When building a package as part of makeroot, make sure it actually gets
  installed.  This is to fix a regression with the switch to USE_DESTDIR=yes.
  Otherwise these packages will get rebuilt later on when needed.

* It is common for calls to mktemp to have 6 placeholders in the template,
  not 4.  Make it so.
