When compiling with gcc8 and -O2, the clever compiler complains:
interface.c: In function ‘interface_ensure_tslabel’:
interface.c:38:3: error: ‘strncpy’ output may be truncated copying 108 bytes
from a string of length 108 [-Werror=stringop-truncation]
Even though this is a false positive, this patch silences the warning
by using memcpy instead of strncpy.
