Remove band.aid that made kbdcontrol lookup keymap files in the syscons
path even under vt, which is no longer useful, since the syscons keymap
files have been converted and committed for use by vt.
Update man-pages to correctly refer to changed pathes and naming conventions
for systems with vt(4) consoles.

Missed comma.
Back-out the references to vt(4) from this man-page. It appears that the
splash support in vt is implemented within the vt driver and does not
depend on splash(4).
