Log message:
mksh: Remove defer-always flag from printf.

Previously this deferred to a printf binary if one was found in $PATH, which
completely defeats the point of using the builtin for performance reasons. We
always create a printf wrapper so one was always found. A nasty side-effect of
this was that with TOOLS_PLATFORM.printf=printf we would end up in a recursive
loop.

Now printf will always use the builtin. Bump PKGREVISION.

Log message:
mksh: Pull in the printf(1) builtin from MirBSD.

Note that we are specifically using -r1.21 as newer versions do not build.

This improves performance on systems that use mksh as the bootstrap shell, due
to widespread use of printf in the pkgsrc infrastructure that previously had
to fork /usr/bin/printf.

Tested on macOS and SmartOS. Bump PKGREVISION.
