[openblas-git] clean up and fix version handling

* Remove unneeded variable (_pkgname isn't used in the source git URL anyway)
* Update max number of thread
* Update pkgver to include actual package version
* Add missing conflicts
* Automatically compute lapack version
* Allow multi-digit lapack major version
