zephyr: config-rsa.h: remove copypasta

MCUboot doesn't need mbedTLS's entropy code (you don't need random
numbers to check a digital signature), but it enables it. This causes
really scary warnings when building entropy.c, since the test entropy
source is enabled:

Delete the bits of the mbedTLS configuration that compile this
file (along with some testing code we don't care about either) to
clean up the warning. This looks like copy/paste code from the initial
mbedTLS config import into MCUboot.
