proc: make config PROC_CHILDREN depend on PROC_FS

Commit b7b9612f9376 ("fs, proc: introduce CONFIG_PROC_CHILDREN")
introduces the config PROC_CHILDREN to configure kernels to provide the
/proc/<pid>/task/<tid>/children file.

When one deselects PROC_FS for kernel builds without /proc/, the config
PROC_CHILDREN has no effect anymore, but is still visible in menuconfig.

Add the dependency on PROC_FS to make the PROC_CHILDREN option disappear
for kernel builds without /proc/.
