check-date-http: stop depending on luci-lib-httpclient

[ilario]

Similar to #720 that was fixed by #722

Installing check-date-http pulls all these dependencies, which are cascading from the dependency from luci-lib-httpclient:

liblucihttp0 cgi-io liblucihttp-lua luci-lib-base rpcd rpcd-mod-file rpcd-mod-luci rpcd-mod-ucode ucode-mod-math ucode-mod-html liblucihttp-ucode luci-base ucode-mod-lua luci-lua-runtime luci-lib-httpprotoutils

The sum of the IPK packages of these dependencies is around 300 kB.

That library is used here:

lime-packages/packages/check-date-http/files/usr/bin/check-date-http

Line 42 in 2d5cb93

local success, response, algo = pcall(http.request_raw, url, httpOptions)

It should be replaced by some other tool, like uclient-fetch, if possible.

Maybe, the solution from #722 can be adapted to work also here.

Somehow, also lime-app pulls all those dependencies.
