adb: do not chown/chmod files pushed to sdcard

Commit "adb: configure /system file permission with fs_config" can cause
'Operation not permitted' errors when pushing files to sdcard because
chown and chmod are not allowed. Omit chown and chmod operations if the
destination directory has sdcard in the group name.
