Wang Nan 0c8c20779c perf report: Don't allow empty argument for '-t'. 
Without this patch, perf report cause segfault if pass "" as '-t':

  $ perf report -t ""

   # To display the perf.data header info, please use --header/--header-only options.
   #
   # Samples: 37  of event 'syscalls:sys_enter_write'
   # Event count (approx.): 37
   #
   # Children    SelfCommand   Shared Object         Symbol
   Segmentation fault

Since -t is used to add field-separator for generate table, -t "" is
actually meanless. This patch defines a new OPT_STRING_NOEMPTY() option
generator to ensure user never pass empty string to that option.
