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

[Han5991]

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
