Rollup merge of #109694 - BelovDV:fix-panic-jobserver-token, r=bjorn3

do not panic on failure to acquire jobserver token

Purpose: remove `panic`.

Rust fails to acquire token if an error in build system occurs - environment variable contains incorrect `jobserver-auth`. It isn't ice so compiler shouldn't panic on such error.
