build: coverage: disable branch coverage generation to avoid hangs in gcov
I have seen hangs with gcov on Jenkins and locally where the processing just
keeps spinning in an infinite loop. From what I have found out this boils down
to using gcov --all-blocks which is what lcov does with branch coverage enabled.
It is supposed to be fixed in gcc 4.8+ but I see this here with 5.3.1. So its
either a regression or not completely fixed. In any case we will ignore branch
coverage for now. I hoped it would work well but it did only for a while and
having line and function coverage is better than having nothing.
