sasview: fix build (#40433)

The package breaks currently breaks with the following message:

```
fixed-output derivation produced path '/nix/store/5dh1mdj027ad8sprk12fqa5h5bpdxs5n-sasview' with sha256 hash '12k1w4yq1mzjxcp2cqb562c7cbwzhi54rsbmgi0fax0i1660q167' instead of the expected hash '05la54wwzzlkhmj8vkr0bvzagyib6z6mgwqbddzjs5y1wd48vpcx'
```

To fix the build the following changes were applied:

* Switched to latest master for now as the older releases have a broken
  `py.test` configuration and altering hashes.

* Added `checkPhase` which invokes `py.test` directly and drops
  duplicated files from `dist/tmpbuild`.

* Rebased the patches `pyparsing-fix.patch` and `local_config.patch` for
  the latest master revision.

Additionally refer to the discussion in #40381 for further reference.
