Fix compiler warning: possible string truncation

Gcc version 7.2.1 complains about string formatting that
may be truncated, generating messages such as:

> fwparam_sysfs.c: In function ‘fwparam_sysfs_boot_info’:
> fwparam_sysfs.c:45:25: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size 242 [-Wformat-truncation=]
>  #define ISCSI_LLD_ROOT  "/sys/firmware/"

Making the destination strings longer fixes this issue.
