This fixes an infinite recursion loop in getFile caused by: 1) `os.Stat(file)` resolves a symlink so that `fileInfo.isDir()` returns True 2) `filepath.Walk()` starts iterating on the root directory (in this case the symlink) 3) `filepath.Walk()` uses `os.Lstat` internally, which does NOT dereference the symlink 4) in the walk func, `f.isDir()` returns False, and the walk func calls `getFile()` on it 5) goto 1 fixes #47 Part-of: https://gitlab.postmarketos.org/postmarketOS/postmarketos-mkinitfs/-/merge_requests/65
