Add local oniguruma submodule

Configure should still allow use of prebuilt onigurumas (whether
system-installed or in a special prefix).  If these are not found, and
configure was not called with `--without-oniguruma`, then use the vendored
oniguruma module.  If configure was called with `--without-oniguruma`, then we
do not build regex functionality into jq.
