GHA/linux: fix thread sanitizer error output

Replace autotools with cmake to avoid libtool wrappers that are changing
`LD_LIBRARY_PATH` in a way incompatible with the thread sanitizer.

To fix the output when the sanitizier is finding something:
```
==51718==WARNING: Can't write to symbolizer at fd 7
 /usr/bin/llvm-symbolizer-18: /home/runner/work/curl/curl/bld/lib/.libs/libcurl.so.4: no version information available (required by /usr/bin/llvm-symbolizer-18)
 /usr/bin/llvm-symbolizer-18: symbol lookup error: /home/runner/openssl/lib/libcrypto.so.3: undefined symbol: __tsan_func_entry
```

After:
```

Also:
- disable memory tracker which turned out to be incompatible with
  the thread sanitizer and detaching threads.
  Ref: #18263 and #curl IRC.
- the job is ~30 seconds faster after this patch.
