- restore i686 compat

Since last update, module compilation was broken. Fix it by adding the old
manually copied headers from kernel compilation

- change package named to linux-$kernelrelease
- remove nice stuff
- use git as source

New install script is bugged when removing the package. It delete the whole
/usr/lib/modules, so this update is required to avoid big issue!

Info file is removed because it's no more needed

Take place and not needed on all servers

- use https url, inside a variable
- forbit invalid pkgname
- doesn't use .sign as they are not supported by makepkg
- upstream patches (rc, stable) are no more prefixed by linux- before downloading
- upstream patches are symlinked instead of copied

This allow refind to detect it automaticaly
