power: supply: test_power: add missing newlines when printing parameters by sysfs

Browse Source 
When I cat some module parameters by sysfs, it displays as follows.
It's better to add a newline for easy reading.

root@syzkaller:~# cd /sys/module/test_power/parameters/
root@syzkaller:/sys/module/test_power/parameters# cat ac_online
onroot@syzkaller:/sys/module/test_power/parameters# cat battery_present
