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: 6e8ccb4f62 ("tools/bpf: properly account for libbfd variations")
