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.

Unless you really know what you are doing, you should say Y here.
The reason is that some programs need kernel networking support even
