RFR: 8272146: Disable Fibonacci test on memory constrained systems

[Christoph Göttschkes]

Hi,

please review this small change to the Fibonacci test case. I added an additional memory requirement for Linux, as I am seeing the test fail on some embedded and emulated devices which do not have enough memory to execute the test case.
The test succeeds on a device with 512MB of physical memory, so I guess this upper bound should be fine. The problem seems to be the kernel memory, as the devices have enough swap space to handle the other test cases.
