please allow ltsp 5.0.39debian1 into testing

[vagrant@freegeek.org]

ltsp is again blocked from migrating into testing, likely due to the
ltsp-client-builder udeb, though this udeb is not used by
debian-installer by default.

it has been in unstable for 16 days now, though is still waiting on the
powerpc, arm, and hppa buildds. no major new issues have been reported.

please allow ltsp 5.0.39debian1 into testing, as it bring ltsp closer in
sync with upstream and ubuntu, includes many new and updated
translations, and fixes a good deal of bugs as well.

thanks for all your work!

live well,
  vagrant
