On a Debian system without python3-distutils install, uwsgi-cgi was
failing to build because it couldn't import sysconfig from distutils.
OpenWrt packages should be using the OpenWrt python not the system
python. In addition we need to use python3 not python2, even when
both are available.

Currently the uwsgiconfig python script append some additional compilation flag based on the host system. This fix some problem related with this by hardcoding usgi_os variable to Linux

* Remove stray LICENSE file added to repo
* Use codeload instead of git
* Add proper (as close as possible) SPDX license
* Drop OpenSSL, PCRE and Libxml2 as dependencies
  Makes it more suitable alternative for small flash devices
* Drop /etc/uwsgi as there's only one config file
* Remove stray /etc/nginx directory
* Reorganize configuration file
* Convert init.d script to use procd
* Hardset 3 threads and processes, seems like a good tradeoff
  between performance and memory usage instead of doing
  auto scaling based on amout of cpu cores/threads
