android-tools-conf-configfs: read android device serial number

Read android serial number value from sysfs node /sys/class/mmc_host/mmc0/mmc0:0001/serial instead of kernel command line. Upstream boot managers e.g., systemd-boot does not populate kernel command line with parameter androidboot.serialno. This approach generalizes and makes serial number population independent of bootloader that loads kernel. Signed-off-by: Vishwas Udupa <[email protected]>
