random numbers on linux

Browse Source 
Switch the default Linux build behavior to use random instead of lrand48,
since lrand48 exhibits some obviously non-random behavior.  random() has
been in glibc for a long time.  Even if no other changes are made to
nethack's random number generator, this will improve the Linux behavior.
