Revert "package/meson: bump to version 1.2.0"

The bump to meson 1.2.0 triggers unexpected build failure of the host
packages, because meson changed the way it passes library search paths
when building natively:

    https://github.com/mesonbuild/meson/commit/59cfbf68e00aa774a9868101f423bd662938c15d
    http://lists.busybox.net/pipermail/buildroot/2023-August/672649.html



As a consequence, the libraries are searched for in the system paths
before being searched in our host-dir, leading to failures when
incompatible libraries are installed in both locations. For example, if
the system has an older version of libglib2 installed, this causes link
failures when one of the glib2 library (e.g. libgio) is linked by path,
but a dependent library (e.g. libgmodule) is linked by name:

    /path/to/host/lib/libgio-2.0.so -L /path/to/host/lib/ -lgmodule-2.0

The first is indeed the one we built and installed in host-dir, but the
second is found in the system path; when it is an older (or more
recent?) version than the one we use, the link fails;

    /path/to/host/lib/libgio-2.0.so: undefined reference to `g_module_open_full'

Since fixing the issue is not trivial, revert to the previous meson
version that did not exhibit the issue.

This reverts commit d06e610d.
