[PATCH 2/3] init-install-efi: fix script for eMMC installation

[Saul Wold <sgw@linux.intel.com>]

From: "Ng, Mei Yeen" <mei.yeen.ng@intel.com>

Running the install option from bootloader to install image to eMMC will fail
with error:
Formatting /dev/mmcblk01 to vfat...
mkfs.fat 3.0.28 (2015-05-16)
/dev/mmcblk01: No such file or directory

This issue impacts both grub and gummiboot install option to eMMC device.
The installation failure is due to the following:
[1] Unable to partition eMMC as the partition prefix 'p' is not appended
The condition checking failed with the additional /dev/ appended with
the target device name.
[2] The partition uuid for boot, root and swap partition is not captured
for eMMC

This fix updated the condition checking and changed the variables to
reference the boot, root and swap partitions for UUID.
