CI: Add 50-minute timeouts to GitHub Actions and Cirrus CI (phpGH-15589)

Currently, there are no explicit timeouts set for CI jobs, which means
the CI jobs will keep running until they are terminated by the task
runner. The current defaults of each provider are:

 - GitHub Actions: 360 minutes[^1]
 - Cirrus CI: 60 minutes[^2]
 - Travis CI: 50 minutes[^3]

On Travis, the timeout is not configurable, and given that our test suite
usually completes within 20 minutes, this commit explicitly sets
timeouts for Cirrus CI and GitHub Actions to 50 minutes as well.
