you can use sudo's option -H.

No, that's the intended behavior.

Once the file has its permissions, it just keeps them.

I guess the reason is that you didn't call texhash/mktexlsr as a user
after creating the HOMETEXMF directory. If you would have done this, the
file would have been created with the same permissions as its parent
directory, ~/texmf, minus t, x, and s, and with you and your group as
its owner.

Once the file exists, mktexlsr doesn't change its permissions or
ownerships; it justs cat's into the file if it has the necessary
priviledges. 

Hm. unsetting HOME in postinst's environment could relieve you from this
inconvenience. But I don't know which other effects it could have.
