Allow inclusion of entropy.h when it's disabled
The build was failing in all.sh component test_no_drbg_no_sha2 because
entropy.h was referencing mbedtls_sha256_context but not including sha256.h
when SHA-256 and SHA-512 were both disabled. This broke query_config.c which
includes entropy.h (and actually all headers) unconditionally.
