tools: add build path support on host_info tool

[fdcavalcanti]

Summary

• tools: add build path support on host_info tool

Adds a build_path argument for when CMake builds are used.
This solves a problem when building the nxdiag tool with CMake.

This is related to this PR on nuttx-apps.

Impact

Impact on user: No.

Impact on build: If using CMake, especially with Espressif devices, this will fix a problem related to the script path. Does not affect Make builds.

Impact on hardware: No.

Impact on documentation: No.

Impact on security: No.

Impact on compatibility: No.

Testing

Build with Make works fine, with CMake it would fail since build and source directory differs.

Building

Make example:

• ./tools/configure.sh esp32h2-devkit:nsh
• Enable CONFIG_SYSTEM_NXDIAG and CONFIG_SYSTEM_NXDIAG_ESPRESSIF
• build

CMake example:

• cmake -B build -DBOARD_CONFIG=esp32h2-devkit:nsh -GNinja
• Enable CONFIG_SYSTEM_NXDIAG and CONFIG_SYSTEM_NXDIAG_ESPRESSIF
• build

Running

Make:

• python3 -B tools/host_info_dump.py /home/fdcavalcanti/nuttxspace5/nuttx --target_info

CMake:

• Need to pass the build directory to '-b'
• python3 -B tools/host_info_dump.py /home/fdcavalcanti/nuttxspace5/nuttx -b build --target_info

On both cases output works fine.
