bugfix: work around ruamel.yaml vendoring issues (#9725)
- Delete references to ruamel.yaml at Spack start-up, if they are present
- ruamel.yaml generates a .pth file when installed via pip that has the
effect of always preferring the version of this package installed at
site scope (effectively preventing us from vendoring it).
- This mechanism triggers when implicitly importing the 'site' module
when the python interpreter is started. In this PR we explicitly delete
references to 'ruamel.yaml' and 'ruamel' in sys.modules, if any, after
we set 'sys.path' to search from the directory where we store vendored
packages. This ensures that the imports after those statements will be
done from our vendored version.
- See #9206 for further details
