fix(dwarf): Allow -2 as a tombstone address (#937)

This updates the `gimli` dependency to give us access to
gimli-rs/gimli#791, in which the address -2
is allowed as a tombstone address in some DWARF files sections. This
lets us extract debug info from some DWARF files that we couldn't handle
before.
