meson: remove deprecated get_pkgconfig_variable
Since meson 0.56, the `get_pkgconfig_variable` has been deprecated. In
meson 0.58 the `get_variable` was enhanced to no longer require the
`pkgconfig` keyword argument. Ensure meson 0.58 is required and update
the usage of all `get_pkgconfig_variable` and `get_variable` to be the
modern variant.
