base-files: sysupgrade fail with eglibc

With eglibc, "ldd busybox" give us
    libcrypt.so.1 => /lib/libcrypt.so.1 (0x774be000)
    libm.so.6 => /lib/libm.so.6 (0x773e4000)
    libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x773c0000)
    libc.so.6 => /lib/libc.so.6 (0x77276000)
    /lib/ld.so.1 (0x774fe000)

Thus /lib/ld.so.1 is not printed by the libs fonction and isn't copied to the 'new' root before pivot root
libs() { ldd $* | awk '{print $3}'; }

With uclibc the last line of "ldd busybox" is
    ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x77ada000)

Don't know for musl!

This patch replace https://dev.openwrt.org/changeset/19167, as glibc is gone
The other way around is to rework libs()

Please apply the fix (mine or another) on trunk and AA
Might fix https://dev.openwrt.org/ticket/12273
