tests: make it harder to lose a race in spinlock-abuse

Browse Source 
* tests/misc/sort-spinlock-abuse: On a busy system, with only 12
pauses of length 0.1 seconds, the buggy (busy-spinlock blocked)
sort would fail to accumulate 1 second of CPU time, and hence
would mistakenly pass.  Increase from 12 to 50.
