dazzle-list-counters installed without package_subdir

dazzle-list-counters needs to be installed respecting package_subdir, so
it doesn't clash with the main installation of libdazzle.

I notice there are not currently any subdirectories in my /usr/bin, so
to avoid setting a precedent for having directories there, let's use
libexec instead when package_subdir is set.
