Check for more symbols before defining HAVE_CLOCK_MONOTONIC in Meson

MacOS has limited support for monotonic clock in its pthread implementation.
When building with Meson, `HAVE_MONOTONIC_CLOCK` is defined despite this.
This PR checks for the existence of the missing function `pthread_condattr_setclock`.
To match parity with AutoTools, it also checks for `clock_getres`.

Fixes #419.
