xap_helper: switch C++ implementation to AGPL-3

GPL-2 approxidate code won't work with the XS/SWIG version, so
it looks like we'll keep calling `git rev-parse' in both
versions for the time being.  Meanwhile, it's more valuable to
be able to take GPL-3+ code from notmuch for thread:{} query
parsing.
