build: require gnulib's fclose module

* bootstrap.conf (gnulib_modules): Explicitly use the fclose module.
This is required, now that gnulib's close module no longer depends
on fclose.  Without this module, we would be exposed to fclose bugs
affecting at least glibc 2.13 and FreeBSD.
Reported by Bernhard Voelker.  Suggested by Eric Blake.
