Increase time to build the ARM image (#24765)

Building ARM image is now done in parallel in case of CI builds
that update dependencies. If the image is not refreshed, then it might
take quite some time - more than the 50 minutes it's been allowed to

This PR increases both timeouts - the self-terminate timeout for
the ARM instance and timeout on the CI job that triggers it.
