[fish] Replace external commands with builtins

Browse Source 
- Use `string collect` instead of cat to get the contents of
  $FZF_DEFAULT_OPTS_FILE. Also, check if the file is readable first.
- Use `string split` instead of cut to set $FISH_MAJOR, $FISH_MINOR.
- Use `string replace` instead of perl to strip leading tabs.
