x86: pageattr-test: remove srandom32 call 

pageattr-test calls srandom32() once every test iteration.  But calling
srandom32() after late_initcalls is not meaningfull.  Because the random
states for random32() is mixed by good random numbers in late_initcall
prandom_reseed().

So this removes the call to srandom32().
