dracut-functions: fixed installing libraries which links to another directory

$ ldd `which bash` | grep ld
/lib64/ld-linux-x86-64.so.2 (0x00007fa1cc3ff000)

$ readlink -f /lib64/ld-linux-x86-64.so.2
/lib/ld-2.12.1.so

So inst_library /lib64/ld-linux-x86-64.so.2 was doing :

(cd "/tmp/initramfs.4uaeD9/lib64" && ln -s "/lib/ld-2.12.1.so"
 "ld-linux-x86-64.so.2")

But, /tmp/initramfs.4uaeD9/lib64 -> /lib... :-S
