• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project follows, as appropriate.
• The changes are appropriately documented (if applicable).
• The changes have sufficient test coverage (if applicable).
• The testsuite passes successfully on my local machine (if applicable).

Summarize your changes:
We're using the host platform instead of the target platform to get the binary path, which results in an incorrect path when making for a different platform (like /path/to/electron.exe instead of /path/to/electron when making for Linux on Windows).

Good catch! If you could also optimize the code, it would be even better.
