* plugins.d/plymouth.c: Break lines, fix whitespace.  Remove
                        unnecessary casts.

  (main) Exit with EX_UNAVAILABLE if plymouth is not found.  Use first
         argument of error() where useful.  Simplify logic of checking
         results of running the ask-for-password command.  Simplify
         assigning value to "plymouthd_argv".
