magma: fix CUDA 11 build

Browse Source 
By default, MAGMA builds against compute capability 3.0 (among other
capabilities). However, support for this capability was dropped in
CUDA 11. This change fixes CUDA 11 support by excluding 3.0.

While at it, this change also adds support for newer compute
capabilities that are not enabled by MAGMA by default (to support
older CUDA versions).
