dev-python/pycuda: add 2021.1, enable py3.10

Also:
- use pep517=setuptools
- depend on nvidia-cuda-toolkit[profiler] wrt bug #748537
- drop two no-op sed expressions (was no-op in previous version too)
- only restrict userpriv when running tests
- EPREFIX->ESYSROOT, these paths aren't stored as far as I can see
- update LICENSE, did not see any reference to GPL-2
- misc cleanups

Unsure if entirely setup right as I don't use this nor dug deep,
and two failing tests on my hardware (with any python version) and
couldn't get the old version's test suite to run right to compare
(90% failures).
