scripts: gen-secure-initramfs: convert absolute symlinks into relative ones

Browse Source 
prpl CI enables CONFIG_IB which runs imagebuilder. Imagebuilder was
failing when trying to copy targets from symlink whose path was
absolute. The solution is to convert absolute symlinks into relative
ones when creating the secure initramfs.
