remote-curl: avoid assigning string constant to non-const variable

When processing remote options, we split the option line into two by
searching for a space. If there is one, we replace the space with '\0',
otherwise we implicitly assume that the value is "true" and thus assign
a string constant.

As the return value of strchr(3P) weirdly enough is a `char *` even
though it gets a `const char *` as input, the assigned-to variable also
is a non-constant. This is fine though because the argument is in fact
an allocated string, and thus we are allowed to modify it. But this will
break once we enable `-Wwrite-strings`.

Refactor the code stop splitting the fields with '\0' altogether.
Instead, we can pass the length of the option name to `set_option()` and
then use strncmp(3P) instead of strcmp(3P).
