nss_files: Add generic code for set*ent, end*ent and file open
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.

27674 code bytes before, 26344 code bytes after, so it is an overall
win despite the extra initialization code.
