feat: zdefend-fix(customize.sh): remove vtap firmware from app data folder & misc changes

Browse source 
current firmware in app data folder only get removed if `fix_vtap_cert` patch is found in app

helpful for restoring old detection behavior

added grep check for magisk.db to check if `com.mbmobile` is in Denylist or not, some devices does not put the app to denylist even though the command is executed

remove restriction for bypassed app
