selftest/wic: update test case test_qemu
This test case boots the image in qemu and checks for mounted partitions.
But the outputs of mount are different between sysvinit and systemd:
sysvinit:
/dev/root /\r\n/dev/sda1 /boot\r\n/dev/sda3 /media\r\n/dev/sda4 /mnt
systemd:
/dev/sda1 /boot\r\n/dev/sda2 /\r\n/dev/sda3 /media\r\n/dev/sda4 /mnt
So check mounted partitions by egrep rather than check output of runqemu.
