test: temporarily adjust the default mount rate limit

Browse Source 
(Hopefully) a temporary workaround for #30573 where starting a user
session when PID 1 is rate limited stalls even after it leaves the rate
limited state:

The issue appeared after ee07fff03b which does a bunch of mounts/umounts
that get PID 1 into a rate limited state, and is frequent enough to be
annoying, so let's temporarily bump the rate limit to alleviate that.
