Qualify relative --configFile value with appDataDir
This behavior had already been implemented prior to this commit, but has
now been tested and improved with refactoring and logging messages.

Note that this approach emulates Bitcoin Core's own behavior. When
running, for example, `bitcoind -conf=rel/path/to/bitcoin.conf`, the
relative path is prefixed / fully qualified by the value of the
`datadir` option. So if `datadir` equals `~/Library/Application
Support/Bitcoin`, then the `conf` option value above would be fully
qualified as

    ~/Library/Application Support/Bitcoin/rel/path/to/bitcoin.conf

If the argument to `-conf` is an absolute path, e.g.
`/tmp/bitcoin.conf`, then that absolute path is used without further
modification or qualification. It is assumed that the rationale for this
behavior is to avoid accidentally running against the wrong conf file
because `bitcoind` was invoked in a different directory than usual or
because a malicious actor replaced the relative conf file with their own
version.

Bisq's new `--configFile` option works (and is now tested to work) in
the same way: relative paths get prefixed by the value of
Config.getAppDataDir(), and absolute paths are processed unmodified.
