tests: Increase the size of the /dev/sda and /dev/sdb test devices.

Previously these were rather small - just 500 MB.  This is too small
to create a btrfs device on aarch64 (where page size may be 64K), and
barely enough even on x86-64.  This change makes both these devices
10 GB, and adjusts a few tests so they continue to pass.
