[PATCH] arch: x86: ia32: ia32_aout.c: Cleaning up missing null-terminate in conjunction with strncpy

From: Rickard Strandqvist
Date: Sat Jul 26 2014 - 17:49:18 EST

Replacing strncpy with strlcpy to avoid strings that lacks null terminate.
And use the sizeof on the to string rather than the from string.
