Alan Maguire 90ae54b4c7 bpftool: Allow bpftool to build with openssl < 3 
ERR_get_error_all()[1] is a openssl v3 API, so to make code
compatible with openssl v1 utilize ERR_get_err_line_data
instead.  Since openssl is already a build requirement for
the kernel (minimum requirement openssl 1.0.0), this will
allow bpftool to compile where opensslv3 is not available.
Signing-related BPF selftests pass with openssl v1.
