    Do not change process UID

    When run with sudo, Anvil changed process real UID
    to SUDO_UID thus easily creating files with different owners.
    This mechanism can confuse some tools (like pip)
    Now, we can almost safely stop changing real UID and run
    prepare as non-root and bootstrap, install, start, status,
    and stop as root.

    Also, this removes dependency on sudo.
