[compiler-rt][hwasan][test] Tweak check in release-shadow.c (#153181)
Since we (Linaro) moved out bots to a new machine, this test has been
failing:
https://lab.llvm.org/buildbot/#/builders/121/builds/1566
Most of the time, the rss difference is greater than 512 on the first
iteration then settles down to 512 for all the rest.
```

```
Given that the test was looking for a diff of at least 513, I guess that
512 is ok too.
For future reference, the original bot host was running this kernel:
Linux 5.15.0-136-generic #147-Ubuntu SMP Sat Mar 15 15:51:36 UTC 2025
aarch64 aarch64 aarch64 GNU/Linux
And the new host:
Linux 6.8.0-64-generic #67-Ubuntu SMP PREEMPT_DYNAMIC Sun Jun 15
20:23:40 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux
Though the new host also has more RAM, so the kernel may be less
aggresive with memory management.
