prevents MCKERNEL_RLIMIT_STACK from overwriting
...
When mcexec reduces a stack, mcexec stores the original RLIMIT_STACK
in environment variable MCKERNEL_RLIMIT_STACK.
A fix to prohibit overwrite of this time.
Therefore, the value of RLIMIT_STACK of the McKernel's process is
decided in the following order.
(1) If environment variable MCKERNEL_RLIMIT_STACK exists; the value.
(2) A value of RLIMIT_STACK in the mcexec starting.

mcexec: add a upper limit of the stack size
...
- When the stack size is greater than 1 GiB, reduced to 10 MiB.
- To achieve a reduction of the stack, restart itself using the exec().
