Tim-Philipp Müller f1bb2c76c6 meson: update for dep.get_pkgconfig_variable() deprecation
... in favour of dep.get_variable('foo', ..) which in some
cases allows for further cleanups in future since we can
extract variables from pkg-config dependencies as well as
internal dependencies using this mechanism.
