This reduces RSS usage if nss_files is not actually used, and can
be used later to make NSS data thread-specific. It also results in
a small code size reduction.
Before:

908 0 0 908 38c nss/files-spwd.os
1090 0 8 1098 44a nss/nss_files_data.os
27674 code bytes before, 26344 code bytes after, so it is an overall
win despite the extra initialization code.
