Fixes for various paths

[Hammster]

Hi,

I've seen that terkelg/tiny-glob#42 was blocked by a failing test, after investigating I could pinpoint it to two cases where the globalyzer could not properly parse the path

Case 1: The glob path included a ../ eg fixtures/../* which was not properly resolved
Case 2: the ./ was part of the pattern and this did not allow to simply subtract the base.length
This create the situation that ./test/*.{js,txt} was interpreted as a st/*.{js,txt}

It would be cool if this finds it's way into tiny-glob :)

Have a great day.

Hey, haha, tbh I don't remember too much of what I did. I know that the static-versus-pattern bit got reworked. I left it as a "WIP" draft because it's breaking – tests changed.

This is a much simpler change, though I feel like posix should be avoided if possible 😬 Without going down another rabbit hole, not sure off-hand what a simpler alternative would be.
