meson: raise required version to 0.44.1

We have already required 0.44 for building clover and swr, so it was
already partially required. This just makes it required across the board
instead of just for clover and swr.

There is a bug in 0.44 which makes it impossible to build mesa in some
configurations, so require 0.44.1 which fixes this.
