fftools/opt_common: Make -sources/-sinks options work without arguments

Browse Source 
The -sources and -sinks options were defined with OPT_FUNC_ARG flag,
which requires an argument. This caused "Missing argument for option
'sources'" error when running ffprobe -sources without arguments.
Removing OPT_FUNC_ARG flag allows these options to work without
arguments, listing all available devices, while still supporting
optional device name argument for filtering specific devices.
