rhg: use a release-mode executable in tests
This allows the rhg build for test-rhg.t to share compiled dependencies
such as hg-core with the hg-cpython build for other tests.
For context, my wrapper script for the typical edit-compile-test
cycle now looks like this:
(cd rust && cargo +nightly-2020-10-04 fmt)
(cd rust && cargo build --release -p rhg)
make --silent local PURE=--rust
python test/run-tests.py --local "$@"

Error: the current ro localization has some rst defects exposed by
moving pager to core. These two warnings about references are expected
until the localization is corrected.
