Log Message:
ctfmerge: fix macOS semaphore implementation

Use dispatch_semaphore_create() if present instead of sem_init().

macOS doesn't actually implement sem_init() (et al)
(even though it provides the prototypes as deprecated).
This was detected by the previous commit to ctfmerge
that added error handling.

Implement ctfmerge's barrier operations in terms of
dispatch(3) APIs such as dispatch_semaphore_create() (et al).

Update tools/compat/configure.ac to find dispatch_semaphore_create().

Fixes ctfmerge on macOS hosts.
