Make logging to journal match what goes to syslog on non-systemd hosts

This makes the log message the same, whether it is sent to systemd's
journal or to syslog.  It retains the extra fields that are passed to
journal, such as MOUDLE=<name> and additional arguments.  Since journal
will reflect messages to syslog, this keeps what goes to syslog
informative instead of the terse 'Ansible module invoked'.

See issue #2461.
Define, when possible, the inventory_dir variable
Limit scope of arguments to service_control() in service module

This fixes handling of arguments (module argument) in service_control().
It is now locally scoped such that modifications to it, in the case of a
systemd host, do not later impact subsequent calls to service_control().
See issue #2449.

Without patch:
ansible-service[6177]: Command /usr/bin/systemctl stop cups cups , daemonize True

With patch:
ansible-service[6475]: Command /usr/bin/systemctl start cups , daemonize True

I also updated the comments to reflect the case where systemd is really
being called.
Fixes for get_remote_head in git module

See issue #2471

This fixes get_remote_head() to be smarter about how to check remote
head.  It checks if it is a remote branch or tag and then checks for the
remote object id associated with it.  If it is sha1, get_remote_head()
returns it as-is since there doesn't appear to be a way to check a
remote repository for a specific object/sha1.  is_remote_tag() is added
to help out the new functionalit in get_remote_head().

In main(), if check_mode is true and version is a sha1, the module now
checks to see if the object is present.
