[PATCH setxkbmap] Few messages added for easier troubleshooting.

[Van de Bugger]

If setxkbmap fails to load rules file, it is not possible to find
out where setxkbmap looks for it. Increasing verbosity level does
not help:

    $ ./setxkbmap -v 10
    Setting verbose level to 10
    locale is C
    Couldn't find rules file (evdev)

The problem fixed by adding two messages: before loading file and
after successful loading. Messages are displayed if verbosity level
is 8 or higher:

    $ ./setxkbmap -v 10
    Setting verbose level to 10
    locale is C
    Trying to load rules file ./rules/evdev...
    Trying to load rules file /usr/local/share/X11/xkb/rules/evdev...
    Couldn't find rules file (evdev)
