[PATCH] lib: fwts_arch: set len to 1 to ensure space for '\0'

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The current code just allocates enough space for the strings
with a trailing spaces, and not enough space for the terminating
'\0' character.  Set len to 1 to ensure we have enough space
allocated.
