Rename embedfs_testdata to internal/testdata

    - Move embedfs_testdata directory to embedfs/internal/testdata
    - Change package name from embedfs_testdata to testdata
    - Update all import paths in test files to use new location
    - Update function calls from embedfs_testdata.GetTestData() to testdata.GetTestData()
    - Fix test expectations for ReadDir("") to match actual billy filesystem behavior
    - Fix file name assertion to match embedded filesystem path structure
    - Add missing newlines to end of test files
