timer: drop ancient macOS fallback

Browse Source 
macOS didn't support clock_gettime until 10.12 which was released
roughly 7 years ago. Since we're breaking support for ancient OSes
anyway, we might as well break some old macOS versions for fun. This
makes 10.12 the minimum supported macOS version.

## System requirements
- A not too ancient Linux, Windows 10 or later, or macOS 10.8 or later.
- A not too ancient Linux, Windows 10 or later, or macOS 10.12 or later.
- A somewhat capable CPU. Hardware decoding might help if the CPU is too slow to
decode video in realtime, but must be explicitly enabled with the `--hwdec`
option.
