configure.ac: fix botched FREAD_READS_DIRECTORIES check 

3adf9fdecf (configure.ac: loosen FREAD_READS_DIRECTORIES test program,
2017-06-14) broke the test program for the FREAD_READS_DIRECTORIES check
by making it syntactically invalid (a dangling ")") and by botching the
type returned from 'main' (a FILE* rather than int). As a consequence,
the test program won't even compile, thus the check fails
unconditionally. Fix these problems.
