Let default arc_c_max be platform dependent
Linux changed the default max ARC size to 1/2 of physical memory to
deal with shortcomings of the Linux SLUB allocator. Other platforms
do not require the same logic.
Implement an arc_default_max() function to determine a default max ARC
size in platform code.
