    nss: Remove <gnu/lib-names.h> include from nsswitch.c
    
    nsswitch.c no longer references any of the *_SO macros provided by
    <gnu/lib-names.h>. The only consumer, __nss_shlib_revision, moved to
    nss_module.c as part of the NSS reorganization in glibc 2.33 (and
    nss_module.c includes the header unconditionally), but the guarded
    include was left behind.
