cmake: check for optional libsigrokdecode features (send EOF)
Implement a feature check for the srd_session_send_eof() routine which depends on the libsigrokdecode version. This test implementation is a little more redundant than necessary, check_symbol_exists() would be preferred instead but would not work in my local setup.
