lib/cmdline: fix get_option() for strings starting with hyphen
When string doesn't have an integer and starts from hyphen get_option()
may return interesting results. Fix it to return 0.
The simple_strtoull() is used due to absence of simple_strtoul() in a boot
code on some architectures.
Note, the Fixes tag below is rather for anthropological curiosity.
