Integration test fails during package build due to stdout mismatch on compiled binary path

[ilmanzo]

Describe the bug some integration tests for release 1.0.0 fails due to exact match required. When building killport as a package, the build system runs test with binaries in a $TMP location, which is random.

As a workaround, tests could match the output vs a regular expression or check the exit value for success/failure.

To Reproduce Steps to reproduce the behavior:

1. Run the command 'cargo test'
2. See the error

running 5 tests
test test_basic_kill_no_process ... ok
Listening on port 8080
Listening on port 8082
test test_signal_handling ... FAILED
test test_dry_run_option ... FAILED
test test_basic_kill_process ... FAILED
test test_mode_option ... FAILED

failures:
