Fix egd and devrandom source configs

./config --with-rand-seed=egd

need to defines OPENSSL_RAND_SEED_EGD and OPENSSL_NO_EGD
so get rid of OPENSSL_NO_EGD (compiles but I did not really test EGD)

./config --with-rand-seed=devrandom

does not work since wait_random_seeded works under the assumption
that OPENSSL_RAND_SEED_GETRANDOM is supposed to be enabled as well,
that is usually the case, but not when only devrandom is enabled.
Skip the wait code in this special case.
