Patch meson.build for wheel build

[kazarmy]

Since Meson doesn't allow direct reading of environment variables, this pr uses sed to patch meson.build for the pypa wheel builds. The patch result should be:

diff --git a/meson.build b/meson.build

The sed suffix trick is from here, here and here.

can't you add some options and use the arguments with the env vars?

option('enable_install', type: 'combo', choices: ['enabled', 'disabled', 'auto'], value: 'auto', description: 'enables or disables the install option.')

and in the CI script we just add -Denable_install=$MESON_INSTALL or even better the variables from the matrix ?

[kazarmy]

The CI build script has this:

    - name: Build rz-bindgen
      uses: pypa/[email protected]

and I don't see how one can add -Denable_install=$MESON_INSTALL to that.

But maybe I should look further
