utils: add osmo_escape_str()

To report invalid characters in identifiers, it is desirable to escape any
weird characters. Otherwise we might print stray newlines or control characters
in the log output.

ctrl_test.c already uses a print_escaped() function, which will be replaced by
osmo_escape_str() in a subsequent patch.

control_cmd.c will use osmo_escape_str() to log invalid identifiers.
