[compiler-rt] [Test][Darwin] Disable test on watchos due to memory restraints (PR #135671)

[via llvm-commits]

https://github.com/thetruestblue created https://github.com/llvm/llvm-project/pull/135671

Because of the nature of this test (mmap stress-test) it tests too large of memory allocations to be stable on watchos. WatchOS has memory limits that can lead to the termination of this process before it reaches the limit set by the flag. It is guaranteed to occur if a test device is under heavy load. disable on watchOS.

 considerations

Because of the nature of this test (mmap stress-test) it tests too large of memory allocations to test on watchos. WatchOS has memory limits that can lead to the termination of this test before it reaches the limit set by the flag. We are going to disable on watchOS for now.
