[OE-core] [PATCH] init-install-efi.sh: Avoid /mnt/mtab creation if already present

[Leonardo Sandoval]

Tests were done in the same manner as described in the bugzilla 
(core-image-sato-sdk image and genericx86-64 machine). In my case, the 
only HW I tested was the minnowboard. The testing consists of booting a 
live image and installing the image. After this patch, installation went 
fine.
