Bug#929915: vala: debian/rules: simplify parallel build

[Helmut Grohne]

Source: vala
Version: 0.42.5-1
Severity: wishlist
Tags: patch

While looking into the vala package, I noticed that it bears unnecessary
complexity for running the bootstrap build. Using dh_auto_* works there
and removes the need for computing DEB_MAKE_PARALLEL. I've attached a
patch to demonstrate that. If you don't like the patch, please close
this bug anyway.
