Fix JavaScriptCore build on systems without anonymous mmapping

Use fastMalloc when neither MMAP nor VIRTUALALLOC are enabled

RegisterFile constructor currently throws #error when both
MMAP and VIRTUALALLOC conditions fail.
On any platform that does not provide these features
(for instance, Symbian),
the fallback should be regular malloc (or fastMalloc).
It is functionally equivalent in this case, even though it may
have certain drawbacks such as lack of dynamic pre-allocation.
