[PATCH] tests/avocado: Make the test_arm_bpim2u_gmac test more reliable

[Thomas Huth <thuth@redhat.com>]

The test_arm_bpim2u_gmac test sometimes fails (ca. 1 out of 20 runs
here) since the disk shows up as /dev/mmcblk1 instead of /dev/mmcblk0
in some runs. No matter of the name in /dev, the major:minor encoding
seems always to be the same, so we can fix this issue by using the
correct major:minor hex number in the "root=" parameter instead.
