Add prng_seeder utility

This binary seeds a FIPS-approved DRBG from /dev/hw_random and then
serves seeds to other processes on the system using a socket
(/dev/socket/prng_seeder) that is passed in by init.

This cherry-pick for tm-qpr-dev omits the command line support
to avoid a dependency problem.

Bug: 243933553
Test: Started under init and verified correct operation using strace
