perf script: Support DSO filter like in other perf tools

Other perf tool builtins already supported a DSO filter.

For example:

  $ perf report --dsos a,b,c

which only considers symbols in these dsos.

Now the DSO filter is supported in 'perf script':

  root@kbl-ppc:~# ./perf script --dsos "[kernel.kallsyms]"
