tools build: Switch to new openssl API for test-libcrypto

Switch to new EVP API for detecting libcrypto, as Fedora 36 returns an
error when it encounters the deprecated function MD5_Init() and the others.

The error would be interpreted as missing libcrypto, while in reality it is
not.

Fixes: 6e8ccb4f624a73c5 ("tools/bpf: properly account for libbfd variations")
