video: Fix calculation of -devparm ticker. The released linuxdoom source had the devparm ticker dots at a spacing of two pixels rather than four pixels (as used in Vanilla Doom). In commit 4a31ec8fcee20e.. I changed this back to four pixel spacing, but forgot to multiply the number of tics to adjust as appropriate. Fix this so that the dots are calculated just like Vanilla Doom is. Thanks to _bruce_ for pointing this out on Doomworld, and to Alexandre-Xavier for questioning my reasoning when I wasn't convinced that the current behavior was wrong. This fixes #360.
