chore(ci): fix failure in detecting compilers in clang-tidy job (#4642)
The clang-tidy job recently started failing.
Last success:
https://github.com/apache/arrow-adbc/actions/runs/30502165159/job/90743952843
First failure:
https://github.com/apache/arrow-adbc/actions/runs/30596999777/job/91051511466
The error is,
> `Could not find the compiler specified in the environment variable CC:
/home/runner/work/arrow-adbc/arrow-adbc/build/tidy/x86_64-conda-linux-gnu-cc.`
Note that path to `x86_64-conda-linux-gnu-cc` is relative to the CWD
which is wrong.
The difference seems to be:
In a successful run, I see:
```
++ readlink -f
/home/runner/miniconda3/envs/test/bin/x86_64-conda-linux-gnu-cc
++ readlink -f
/home/runner/miniconda3/envs/test/bin/x86_64-conda-linux-gnu-c++
```
In a failed run, I see:
```
++ readlink -f x86_64-conda-linux-gnu-cc
++ readlink -f x86_64-conda-linux-gnu-c++
```
A notable difference between these two environments is that the last
working build used `gcc_linux-64=14.3.0` whereas the failures started
after `gcc_linux-64=14.4.0` showed up.
