Run only top-level recursive lcov
This is the way lcov was intended to be used. It is much faster and
more robust and makes the makefiles simpler than running it in each
subdirectory.
The previous coding ran gcov before lcov, but that is useless because
lcov/geninfo call gcov internally and use that information. Moreover,
this led to complications and failures during parallel make. This
separates the two targets: You either use "make coverage" to get
textual output from gcov or "make coverage-html" to get an HTML report
via lcov. (Using both is still problematic because they write the same
output files.)
