Fix a compilation error with 10.11 SDK.

Fix a compilation error with 10.11 SDK.

TASK_VM_INFO_REV1_COUNT is defined in the 10.12 SDK, but has a different name in
the 10.11 SDK (TASK_VM_INFO_COUNT). Instead of using it, just use
sizeof(ChromeTaskVMInfo) / sizeof(natural_t), which works for all SDK versions.
