build: Make --with-json-audit the default
Thanks to Rowland for a clear description of the behaviour for the smb.conf manpage.
This means that those not wanting to link to libarchive will just need to
build --without-json-audit.
In general, we prefer that optional libraries be required by default
so that they are not accidentially missed, particularly in packages.
