fs: fix ENOTDIR in globSync when file is treated as dir

`fs.globSync` failed with `ENOTDIR` when a path component in a glob
pattern was a file but used as a directory (e.g., 'foo{,/bar}' when
'foo' is a file).

This change aligns `getDirentSync` with the asynchronous `getDirent`
by wrapping the `lstatSync` call in a `try-catch` block to safely
return `null` on such errors.

Fixes: #61257
