ipa: rpi: Use std::abs()

As explained in the coding style document, usage of std::abs() is
preferred over abs() or fabs() as it picks the correct function based on
the argument type. Replace calls to abs() and fabs() with std::abs() in
the Raspberry Pi algorithms.

This fixes a reported warning from clang:

../src/ipa/rpi/controller/rpi/awb.cpp:508:6: error: using integer absolute value function 'abs' when argument is of floating point type [-Werror,-Wabsolute-value]
        if (abs(denominator) > eps) {
            ^
../src/ipa/rpi/controller/rpi/awb.cpp:508:6: note: use function 'std::abs' instead
        if (abs(denominator) > eps) {
            ^~~
            std::abs
