uhd: math: Replace wrap-frequency math with a single function
In multiple places in the UHD code, we were doing the same calculation
for a wrapped frequency (wrap it into the first Nyquist zone). This math
was using boost::math, too. Instead of editing every instance, we create
a new function, uhd::math::wrap_frequency(), and replace all of its
separate implementations with this function. The new function also no
longer relies on boost::math::sign.
