This is a bad check. Consider the following example:
| $ export LUA_PATH="$LUA_PATH;third_party/luarocks/src/?.lua;;"
| $ ./extra/dist/tarantoolctl rocks search --all > valid.out
| $ wc valid.out && echo "Non-empty output"
| 17835  56986 605906 valid.out
| Non-empty output
| $ ./extra/dist/tarantoolctl rocks search all --force > invalid.out
| $ diff -u valid.out invalid.out && echo "Outputs are the same"
| Outputs are the same

You need to check whether 'all' key exists in keyword_arguments, not to
search 'all' substring in arg tables values.
