Cabal file not found for when hs-source-dirs = "."

[brandonchinn178]

Describe the bug
When I set hs-source-dirs: . in the cabal file, modules don't find the cabal file correctly, specifically:

Found .cabal file a/b/foo.cabal, but it did not mention a/b/Foo/Bar.hs

To Reproduce

-- a/b/foo.cabal
library
  exposed-modules:
    Foo.Bar
  hs-source-dirs: .
  default-extensions: ImportQualifiedPost

-- a/b/Foo/Bar.hs
module Foo.Bar where
import Data.List qualified as List

Expected behavior
Should find the appropriate cabal file

Environment

• OS name + version:
• Version of the code:

Additional context
Problem seems to be here:

ormolu/src/Ormolu/Utils/Cabal.hs

Lines 171 to 175 in 5e66897

	(takeDirectory cabalFile </>) <$> prependSrcDirs (dropExtensions m)
	where
	prependSrcDirs f
	| null hsSourceDirs = [f]
	| otherwise = (</> f) . getSymbolicPath <$> hsSourceDirs

Where the final path should be normalized:

>>> "foo" </> "." </> "A.hs"
"foo/./A.hs
