status: print stash info with --porcelain=v2 --show-stash

The v2 porcelain format is very convenient for obtaining a lot of
information about the current state of the repo, but does not contain
any info about the stash. git status already accepts --show-stash but
it's silently ignored when --porcelain=v2 is given.

Let's add a simple line to print the number of stash entries but in a
format similar in style to the rest of the format.
