strstarts: helper function for !strncmp(str, prefix, strlen(prefix))

Impact: minor new API

ksplice added a "starts_with" function, which seems like a common need.
When people open-code it they seem to use fixed numbers rather than strlen,
so it's quite a readability win (also, strncmp() almost always wants != 0
on it).

So here's strstarts().
