configure.ac: Remove unused function and header checks.

This removes the following definitions from config.h:

   CTIME_R_THREE_ARGS
   GETHOSTBYADDR_R_SEVEN_ARGS
   GETHOSTBYNAME_R_FIVE_ARGS
   HAVE_ISBLANK
   HAVE_MKSTEMP
   HAVE_STATFS
   HAVE_STATVFS
   HAVE_SYS_MOUNT_H
   HAVE_SYS_PARAM_H
   HAVE_SYS_STATVFS_H

These were all either unused or unnecessarily used.

(cherry picked from commit 3777e4887c286282b5e24b42328a6a660d7360c8)
