Add meson option to use gettext for translations in .policy files

[bluca]

Disabled by default. Will be used in Debian/Ubuntu and derivatives,
where this patch has been carried out-of-tree for ~15 years.

Fixes #35

Operating system fedora 40.
After this patch is installed, the policy prompt is correct for the first time every time the polkit service is restarted. After that, only English is displayed.

I noticed that you added judgment to the result value. I can just tell you the result value in these two executions.

Is the problem with the GUI pop-up that you showed previously solved with the latest code changes in this PR?

No, this PR didn't fix it.

The phenomenon remains the same.

Ok thanks, I've switched this to a disabled-by-default meson option. We can enable this in Debian and derivatives, and it can be kept disabled in Fedora and derivatives.

@jrybar-rh gentle ping - this is disabled by default so shouldn't affect Fedora, but it would allow us in Debian/Ubuntu to drop a downstream patch that we have been carrying for more than 10 years. Thanks!
