Message:

stripping: add libnss_*.so* into online_usrlib

Glibc loads these "NSS modules" (see man 5 nss) on startup. This is
implemented with something like dlopen() so "ldd" won't show them up.
So they should be considered "online" here.

Without this addition, overwriting libnss_files-2.33.so reproducibly
triggers a crash during jhalfs runs where stripping is enabled. In
manual builds, it reproducibly triggers a crash exiting from chroot.

After this change I reran stripping 5 times and there was no crash
observed.
