meson: Allow absence of abi-compliance-check tools

Fixes:

```
Configuring config.h using configuration
Dependency gtest found: YES 1.12.1 (cached)
Dependency gmock found: YES 1.12.1 (cached)
Program abi-dumper found: NO
Program abi-compliance-checker found: NO

../meson.build:85:4: ERROR: Tried to use not-found external program in "command"
```

Tested by issuing `meson setup build && meson compile -C build` both
without and with `abi-dump` and `abi-compliance-checker` installed.
I verified that in the former case we don't fail setup and in the latter
case we check for ABI compliance.
