lcov: set default for branch coverage data to disabled

Collecting branch coverage data can significantly slow down
coverage data collection and processing of data files. Assuming
that most users are more interested in line/function coverage,
change defaults to not collect/process branch coverage data.

Users can still override this default using lcov_branch_coverage=1
in the lcovrc file or command line option --rc lcov_branch_coverage=1
