misc/reboot: skip TestRepeatBootstrap on short builders

This test is slow and resource-intensive, and will rarely catch
failures. It is important to run sometimes, but probably a waste of
time on smaller (and especially reverse) builders.
Rather than hard-coding a list of small builders, only run it on the
longtest builders.

Fixes #35233
Fixes #30892
Fixes #49753
