panic() instead of logrus.Fatal() in init funcs
Some packages were using `logrus.Fatal()` in init functions (which logs the error,
and (by default) calls `os.Exit(1)` after logging).

Given that logrus formatting and outputs have not yet been configured during the
initialization stage, it does not provide much benefits over a plain `panic()`.

This patch replaces some instances of `logrus.Fatal()` with `panic()`, which has
the added benefits of not introducing logrus as a dependency in some of these
packages, and also produces a stacktrace, which could help locating the problem
in the unlikely event an `init()` fails.

Before this change, an error would look like:

    $ dockerd
    FATA[0000] something bad happened

After this change, the same error looks like:

    $ dockerd
    panic: something bad happened
