openblas: .libs() uses self.libraries attribute (#48942) 
Currently this is hardcoded to the same value as listed in the class
definition. If one ever overrides this attribute, such as:

```
packages:
  openblas:
    package_attributes:
      libraries = [ 'libopenblaso64', ]
```

this patch will make sure that override also in the
`spec['openblas'].libs()` call. (Which happens in `hypre`, likely
others).

( see
https://spack.readthedocs.io/en/latest/packages_yaml.html#assigning-package-attributes
)

Thanks to becker33 for debugging help in Slack
