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

commit 5b245985a6de5ac18b5088c37068816d413fb8ed upstream.

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")
