Fix up ignore patterns by only matching exact files

A difference between `glob` and `tinyglob` is how `ignore` is applied.
`glob` has an exception that only applies `.../*` patterns to files.
`tinyglobby` doesn't make this distinction and hence that'd also exclude
directories to be traversed. Patterns have been adjusted to account for
this.
