rng-tools: fix rngd blocks system shutdown
fix-rngd-fail-to-stop.patch is added to fix rngd blocks system shutdown
issue. But it causes rngd doesn't release CPU and causes 100% CPU
usage, so drop it.
The block shutdown issue is caused by comit [
7cb64b9fe1 rng-tools: start
earlier in the boot process] which updated rngd.service. Revert the
modification of rngd.service.
Update sed expressions in do_install as well which fails to replace
second match in one line.
