remove: unnecessary permanent logs in libzygisk.so

This commit changes logs from LOGI to LOGD. This change is explained by the fact that libzygisk.so logs inside the app, which is easily detectable, and LOGI is not removed in release builds, where LOGD and LOGV are, being a better solution in the meanwhile.
