I didn't have time to look at the current trigger code, but IIRC it is
now not a file trigger, but called explicitly. Then, this could be
solved by a flavor: 

- Without additional arguments, dh_installtex activates a trigger which
  calls mktexlsr only for $TEXMFMAIN

- With a flavor "texmfdist", a different trigger is activated which
  calls mktexlsr on $TEXMFDIST

Even without this, I tend to support activating the mktexlsr trigger.

I'm not so sure with this. IIRC, currently formats are only built once
when installing many packages in a row, or upon upgrade. With the
trigger, this is deferred, but doesn't change - and in the worst case,
the upgrade (or more likely installs) are split into different dpkg
runs, and each format but one is rebuilt twice...
