Remove timeout for VCS status output

This was promptoglyph's raison d'être, but modern Git has an "fsmonitor"
feature that gets you _really_ fast repo status by using a daemon
(like Watchman) to keep track of which files might have changed and need
another stat(). This system also doesn't like if you murder `git status`
while it's in the middle of doing its thing.

With this feature gone, I should probably revisit zsh's `vcs_info` and
see how it compares (both in output and performance) to this tool.
