tty/vt: consolemap: use ARRAY_SIZE(), part II.

Browse Source 
The code still uses constants (macros) as bounds in loops after commit
17945d317a (tty/vt: consolemap: use ARRAY_SIZE()). The contants are at
least macros used also in the definition of the arrays. But use
ARRAY_SIZE() on two more places to ensure the loops never run out of
bounds even if the array definition change.
