handle host detector with custom error handler and open_basedir

[brettmc]

if open_basedir is configured such that files that the host detector tries to open are denied with a php warning, and a custom error handler is installed which converts warnings to exceptions, an unhandled exception occurs.
add a test for this, and some try/catch/ignore blocks around the code that can trigger this.

Closes: #1450
Replace: #1451

IMO we should disable the error handler instead.

set_error_handler(static fn() => true);
try {
    if (($content = file_get_contents($file)) !== false) {
        return trim($content);
    }
} finally {
    restore_error_handler();
}

These checks are no longer needed.
