perf strlist: Allow substitutions from file contents in a given directory

So, if we have an strlist equal to:

   "file,close"

And we call it as:

   struct strlist_config *config = { .dirname = "~/strace/groups", };
   struct strlist *slist = strlist__new("file, close", &config);

And we have:
  $ cat ~/strace/groups/file
  access
  open
  openat
  statfs

Then the resulting strlist will have these contents:

  [ "access", "open", "openat", "statfs", "close" ]

This will be used to implement strace syscall groups in 'perf trace',
but can be used in some other tool, thus being implemented in 'strlist'.
