hurd: Fix local PLT
* include/sys/random.h (__getrandom): Add hidden prototype. * stdlib/getrandom.c (getrandom): Rename to hidden definition __getrandom. Add weak alias. * sysdeps/mach/hurd/getrandom.c (getrandom): Likewise. * sysdeps/unix/sysv/linux/getrandom.c (getrandom): Likewise. * sysdeps/mach/hurd/getentropy.c (getentropy): Use __getrandom instead of getrandom.
