gkeyfile: Rework preconditions to avoid unreachable branches

Browse Source 
It’s a programmer error for `NULL` to reach `is_group_name()` or
`is_key_name()`, so rework the preconditions so that all programmer
error checks are wrapped in a `g_return_if_fail()`. The coverage
scanning is set up to ignore anything inside that.
