fix(ng-update): avoid error if project has folder ending with style e…

…xtension

Previously, we always queried for `.css` and `.scss` files in the whole
workspace. We relied on `glob` for this, but did not disable folder
matching. Hence, it could happen that in some cases the migration rule
tried reading content from a directory (resulting in `EISDIR` error).

Additionally, we always queried for files in the actual workspace root.
This has downsides and is not correct because it could mean that
stylesheets from other projects are accidentally read (in case of a
monorepo for example).

Fixes angular#18434.
