build: Add missing function checks for optional daemon features.

Browse source 
* config-daemon.ac: Check for lchown, posix_fallocate, vfork,
  sched_setaffinity, statvfs, nanosleep, and strsignal.  As a side
  effect, this enables daemon features depending on the corresponding
  feature test macros.
