package/pkg-meson.mk: add support for fortran cross-compilation

python-scipy is moving to a meson build infrastructure, and requires
fortran cross-compilation. This commit extends the cross-compilation
configuration file generated for use by meson to add the "fortran",
"fortran_args" and "fortran_link_args" properties.
