libRand: bs_rand_main: Make functions declarations prototypes

Add an explicit (void) to functions without parameters,
in their declarations, this makes them actual prototypes
which tells the compiler they get no arguments,
instead of an unknown number of arguments.
This avoid possible build warnings, and possible
missaligments in the callers.
