    Revert "Bug 40093: Ensure application-services libs do not include libc networking symbols"
    
    This reverts commit 82ad6be56ef54a27da654d7ea879f8dff5fda900.
    
    We need to bump Rust to 1.45 for #40115 and thus, we need to back out
    this patch again and try finding a fix for #40114 instead.
