ubi-utils: use 'stat(2)' instead of 'lstat(2)'
The UBI tools refuse to work with symlinks like '/dev/ubi/bootloader -> ../ubi0_2' because they use 'lstat(2)' and get information about the symlink but not about the device. This is unwanted and fixed by this patch. This patch renames 'struct stat stat' variables to 'st' to avoid compilation errors.
