perf script: Remove the time slices number limitation
Previously it was only allowed to use at most 10 time slices in 'perf
script --time'.
This patch removes this limitation.
For example, following command line is OK (12 time slices)
perf script --time 1%/1,1%/2,1%/3,1%/4,1%/5,1%/6,1%/7,1%/8,1%/9,1%/10,1%/11,1%/12
