Increase timeout for ADB backup/restore of SharedStorage.

It previously used a backup timeout of 5 min, and restore timeout of 1
min, that would always timeout if the files on shared storage were big.
Now increase both to 60 minutes.

Bug: 37201952

Test: adb backup -shared && adb restore backup.ab
