random: move random_min_urandom_seed into CONFIG_SYSCTL ifdef block
Building arm allnodefconfig causes the following build warning:
drivers/char/random.c:318:12: warning: 'random_min_urandom_seed' defined but not used [-Wunused-variable]
Fix the warning by moving 'random_min_urandom_seed' declaration inside
the CONFIG_SYSCTL ifdef block, where it is actually used.
While at it, remove the comment prior to the variable declaration.
