Subject: Add builtin ccache support, enabled by default

Add builtin support for using ccache in pbuilder and enable it by
default.  Ship a new /var/cache/pbuilder/ccache dir and bind-mount and
chown it to BUILDUSERID at build time.  Install/remove ccache
automatically on create/update if CCACHEDIR is set/unset.  Update docs
and remove old ccache config example.  Add a NEWS entry featuring the
change.
