Patch for unlocking builtin Dropbox/Google Drive support

[imax]

I've sent a pull request to kobopatch repo a few days ago (https://github.com/pgaskin/kobopatch-patches/pull/139).

Firmware has a hardcoded list of device models on which these features are enabled. The patch simply changes device model checks to always return "true", effectively enabling them on any device.

I've applied this to my Kobo Libra 2 and Google Drive sync works perfectly well.

Initially I was setting out to find a way to enable them via some simple config changes, but, sadly, it turned out that libnickel simply does

return this->isFrost() || this->isEuropa();

If you happen to know of a less intrusive way to achieve the same without patching libnickel.so after every update - please do let me know!
