nicoo e64d3f60fb nixos/modules/security/rngd: Disable by default
`rngd` seems to be the root cause for slow boot issues, and its functionality is
redundant since kernel v3.17 (2014), which introduced a `krngd` task (in kernel
space) that takes care of pulling in data from hardware RNGs:

>     hwrng: create filler thread
>
>     This can be viewed as the in-kernel equivalent of hwrngd;
>     like FUSE it is a good thing to have a mechanism in user land,
>     but for some reasons (simplicity, secrecy, integrity, speed)
>     it may be better to have it in kernel space.
>
>     This patch creates a thread once a hwrng registers, and uses
>     the previously established add_hwgenerator_randomness() to feed
>     its data to the input pool as long as needed. A derating factor
>     is used to bias the entropy estimation and to disable this
>     mechanism entirely when set to zero.
