Handle glibc-hwcaps on ppc64le on CentOS/RHEL/Rocky 8 for tests/replace-add-needed.sh (fixes #406)

ldd(1) usually returns for ELF binaries output like this:

	libc.so.6 => /lib64/libc.so.6 (0x00007fbacd6ca000)

But with glibc-hwcaps, the output could also be like this:

	libc.so.6 => /lib64/glibc-hwcaps/power9/libc-2.28.so (0x00007fffb5800000)
