libclc: Fix absolute symlinks in sysroot

This helps in creating relative symlinks

Fixes sstate errors e.g.
ERROR: sstate found an absolute path symlink /home/khem/yoe/build/tmp/work/aarch64-linux/libclc-native/21.1.0/sysroot-destdir/home/khem/yoe/build/tmp/work/aarch64-linux/libclc-native/21.1.0/recipe-sysroot-native/usr/share/clc/gfx90c-amdgcn-mesa-mesa3d.bc pointing at /home/khem/yoe/build/tmp/work/aarch64-linux/libclc-native/21.1.0/build/tahiti-amdgcn-mesa-mesa3d.bc. Please replace this with a relative link.
