sys/random/kconfig: remove HWRNG default in backend choice 
For now we match the Makefile.dep default, ignoring if the platform
presents a Hardware RNG.

39b8cdf760 sys/random: default to musl LCG 
In [0] the paper concludes with

> The Knuth LCG is the most efficient general purpose generator that
> provides decent statistical quality.
> It is simple and lean enough to run on very constrained devices.

So let's select `prng_musl_lcg` to be the default PRNG instead of
`prng_tinymt32`.

This gives a good chunk of memory on e.g. `samr21-xpro`:

prng_tinymt32
-------------

   text	   data	    bss	    dec	    hex	filename
  26452	    136	   2824	  29412	   72e4	tests/rng/bin/samr21-xpro/tests_rng.elf

prng_musl_lcg
-------------

   text	   data	    bss	    dec	    hex	filename
  26208	    136	   2808	  29152	   71e0	tests/rng/bin/samr21-xpro/tests_rng.elf

2f423473fc sys/random: add option to use HWRNG as source of randomness 
Add the `prng_hwrng` module to enable the HWRNG as source of all randomness, not just
for seeding a PRNG.

saves ~260 bytes compared to using tinymt32.
