Previously, the time percent slice needs an index to specify
which one the user wants.
While it may be easy for using if the index can be omitted.
So with this patch, for example,
perf report --stdio --time 10%/1 should be equivalent to
perf report --stdio --time 10%

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
