Nicer share target for default print service

This was suggested by the share sheet team and I checked that this
permission only narrowly adds the ability to present a nicer share
target.

The default print service cannot be renamed "print" as the name of the
app shows up on other print UI.

Bug: 150646365
Test: Checked permission after boot
