Simplify locale configuration

[jdebp]

Per https://unix.stackexchange.com/a/578832/5132 there's no need for --locale or a HELPCOVID_LOCALE environment variable, and these are just superfluous knobs. Just call setlocale() with "" to set the locale from the standard LC_* and LANG environment variables. Users can set locale with those standard environment variables, on the command line or in service definitions for systemd and otherwise, in the ways that they already expect.

The locale could be different and certainly depends upon the Accept-Language <https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language> HTTP hearder. Think of a helpcovid running near the French German border. German people want to read german pages, French people want to read french pages. Especially old persons.

That doesn't need the HELPCOVID_LOCALE or --locale mechanisms, that this issue addresses, and they help not one whit with that. Setting the standard environment variables is entirely adequate for the task of specifying the initial locale.

Usually a webapp would permit an http get parameter to set the locale e.g. https://covidhelp.space/index.html?hl=en
