Fix missing PCRE2 dependency in R 3.x builds for RHEL 9

[glin]

In https://github.com/rstudio/r-builds/pull/133, I missed an update to the PCRE lib dependencies for RHEL 9. The R 3.5/3.6 builds require both PCRE1 and PCRE2, but only PCRE1 was a dependency, so the tests failed when installing the test package.

But unfortunately, the exit codes from the tests weren't being propagated correctly, so CI wasn't catching this earlier. (I only realized this while adding the R Docker images in https://github.com/rstudio/r-docker/pull/85, which I also forgot to add CI support for, oops)

• Fix exit code propagation by using docker-compose run instead of docker-compose up, which exits with a 0 even if the container exits with a non-zero exit code. docker-compose up has a --abort-on-container-exit flag to propagate the exit code I think, but docker-compose run makes more sense anyway, and can automatically clean up containers as well.

  With docker-compose run, a non-zero exit code is returned when the container errors out:
