[dlls/msacm/format.c] Strncpy elimination.

[Peter Berg Larsen]

I have been checking the usage of strncpy, replacing where apropriate with
a memcpy or lstrcpyn[AW]. The first raw diff was 100kb, so there is bound
to be one or two slips. These are the first batch which I found to be
obvious, correct, and didnt need a special comment. Note with correct I
mean if there was a \0 bug before then it still there.

Changelog:
	Janitorial Task: Check the usage of strncpy/strncpyW.
