sptests/sp36: Remove obsolete test program

It tests the (never really working) strict order mutex option. That
option does not exist any more. Mutexes by other good means (spmutex01,
spsem*).

Update #3406.

This is a simple test program to demonstrate strict order mutex.
1)What's strict order mutex ?
In rtems,when a task release a priority_inheritance or
priority ceiling semaphore,the kernel detect whether
this task holds priority_inheritance or priority
ceiling semaphore, if not, set the priority of task
back to real priority of task.
This method is right, but in theory, we would like
to reset the priority after releasing the mutex if
releasing it in LIFO order.Do it like this can decrease
the blocking time of a higher priority task .
2)How to enable "strict order mutex " ?
When configuring the rtems , add
ENABLE_STRICT_ORDER_MUTEX=1
to your configure parameter.
3)About this test program
T0,T1,S0,S1
T0,priority 4
T1,priority 1
S0,priority inheritance
S1,priority ceiling,priority ceiling 1
1,T0 obtain S0 then obtain S1, priority of T0 should be improved to 1
2,T0 try to release S0, but not in strict order, return error code
3,T0 release S1,the priority of T0 back to 4
4,T1 try to obtain S0
5,T1 should be blocked and the priority of T0 should be improved to 1
6,T0 release S0
7,T1 obtain S0
8,OVER.
