utils: spkmodem: suggest to use parec instead of parecord
Using recent versions of parecord produces the following: Failed to open audio file. According to the manual: -r | --record Capture audio data and write it to the specified file or to STDOUT if none is specified. If the tool is called under the name parec this is the default. so we suggest parec instead.
