wireprotov2server: use our JSON encoder

Python's json module doesn't like to encode bytes instances.
This makes this code difficult to work with Python 3.

We simply swap in Mercurial's JSON encoder to work around it.

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
