[PATCH v2 2/3] selftests/bpf: Add test_progs opts for sign-file and kernel priv key + cert

[Roberto Sassu <roberto.sassu@xxxxxxxxxx>]

According to the logs of the eBPF CI, built kernel and tests are copied to
a virtual machine to run there.

Since a test for a new helper to verify PKCS#7 signatures requires to sign
data to be verified, extend test_progs to store in the test_env data
structure (accessible by individual tests) the path of sign-file and of the
kernel private key and cert.
