hildon-im-protocol: add HILDON_IM_LONG_PRESS_SETTINGS_NAME to ATOM_NAME

The constant was missing from the list, which should currently be 14
items per src/hildon-im-protocol.h, but we had only 13.

This resulted in this atom being registered with an empty name in X:

    #0  0x00007ffff73c0ac0 in XInternAtom (dpy=0x555555581590, name=0x0, onlyIfExists=onlyIfExists@entry=0)
        at ../../src/IntAtom.c:166
    #1  0x00007ffff69b538b in hildon_im_protocol_get_atom (atom_name=atom_name@entry=HILDON_IM_COM) at hildon-im-protocol.c:73
    #2  0x00007ffff78b27c8 in hildon_im_ui_send_communication_message (self=0x5555555c23a0, message=19) at hildon-im-ui.c:2202
    #3  0x00007ffff199ff0f in hildon_im_keyboard_monitor_enable (plugin=0x55555564e8b0, init=<optimized out>)
        at hildon-im-keyboard-monitor.c:186
    #4  0x00007ffff78b0ab3 in init_persistent_plugins (self=0x5555555c23a0) at hildon-im-ui.c:439
    #5  0x00007ffff78b0ab3 in hildon_im_ui_init (self=0x5555555c23a0) at hildon-im-ui.c:1901

And confuses me:

    type:95
    format:
    Atom name length: 0
    Atom name:

And Qt:

    qt.qpa.xcb: Unhandled client message:  ""

Let's fix it by adding it to the list of constants.

debian/changelog: bump for 2.1.67
