__fish_pwd: Just always define the cygwin version

Browse Source 
This called `uname` just to check if we *should* shorten "cygdrive"
directories.

That's more annoying than just doing it by default - on my system `pwd
| string replace` takes about 100 *micro*seconds, and this is done
once per prompt. Anyway, using $PWD further speeds it up to ~30
microseconds (compared to 10-20 for just `pwd`). This is hard to
measure because it's heavily impacted by system hitter.

The alternative is to ask cygwin to ship this feature as a patch.
