random: don't forget compat_ioctl on urandom

Browse Source 
commit 4aa37c463764052c68c5c430af2a67b5d784c1e0 upstream.

Recently, there's been some compat ioctl cleanup, in which large
hardcoded lists were replaced with compat_ptr_ioctl. One of these
changes involved removing the random.c hardcoded list entries and adding
a compat ioctl function pointer to the random.c fops. In the process,
urandom was forgotten about, so this commit fixes that oversight.
