[PATCH 3/3] cli: fix clang build warnings

[Jani Nikula]

Fix the following warning produced by clang 3.5.0:

notmuch-search.c:730:25: warning: initializing 'void *' with an
expression of type 'const notmuch_opt_desc_t (*)[4]' discards
qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
        { NOTMUCH_OPT_INHERIT, &common_options, NULL, 0, 0 },
                               ^~~~~~~~~~~~~~~
1 warning generated.

---

I'm not really happy with this one. An alternative would be to drop
const from common_options, but I'm not happy with that either. And I'm
not happy with the warning. :(
