Sergey Ulanov 47210f480f [Fuchsia] Always call zx_vmo_replace_as_executable() in OS::Allocate() 
OS::Allocate() previously was calling zx_vmo_replace_as_executable()
when executable access is requested. This breaks the case when the
OS::SetPermission() is called to mark that memory as executable later.
Updated it to call zx_vmo_replace_as_executable() for all VMOs.

This solution is not ideal, but it's consistent with other platforms,
so it's acceptable short-term.
