pine64-pinephone/pinetab: upower: add missing replaces
Fix regression from !2193 (merged):
(12/14) Installing device-pine64-pinephone-upower (0.28-r0)
ERROR: device-pine64-pinephone-upower-0.28-r0: failed to rename etc/UPower/UPower.conf/.apk.1f54ddb1c2b28278d51b2d8f7a7fcc7fd765f6736ffac588 to etc/UPower/UPower.conf/UPower.conf.
I'm verifying that it works on the pinephone, then merging.
