minimal configurations where EPOLL, PERF_EVENTS, etc are disabled, but NET is enabled, are failing to build with link error: kernel/built-in.o: In function `bpf_prog_load': syscall.c:(.text+0x3b728): undefined reference to `anon_inode_getfd'
fix it by selecting ANON_INODES when NET is enabled

I understand that 'select' is highly non-recommended for all good reasons, but here 'depends on' is very user unfriendly, since ANON_INODES is a hidden config that users cannot select directly.
