libcamera: utils: Avoid infinite recursion with strtod()

When the C library doesn't provide local object support, the
utils::strtod() function simply calls strtod() from the C library. The
current implementation does so incorrectly, and calls utils::strtod()
instead, resulting in infinite recursion. Fix it with a proper namespace
qualifier.
