Romain Naour 6f9e83f5f7 support/testing: test_ubi: reduce the rootfs.ubi size to 64M to match the Qemu emulated flash device
The size of the cfi flash device emulated by Qemu is 64M not 128M [1].
Since Qemu >= 4.0, the size of the device must match the size of the block backend [2].

Fixes:

  qemu-system-arm: device requires 67108864 bytes, block backend provides 134217728 bytes
