vm_core.h (rb_execution_context_t): interrupt_mask size to match interrupt_flag

Browse source 
rb_atomic_t is 32-bit on 64-bit platforms (including the popular
x86-64 Linux), so save 4 bytes on this structure.  This doesn't
result in any final size reduction due to padding, yet, but
future changes are possible to shrink rb_execution_context_t
