ipc/sem: use flexible array in 'struct sem_undo'
Turn 'semadj' in 'struct sem_undo' into a flexible array.
The advantages are:
- save the size of a pointer when the new undo structure is allocated
- avoid some always ugly pointer arithmetic to get the address of semadj
- avoid an indirection when the array is accessed
While at it, use struct_size() to compute the size of the new undo
structure.
